Lock Change Cost Breakdown: Labour Rates vs. The Price of Parts

When you ask "how much to change locks," the final figure on your invoice is made up of two key components: the locksmith's labour and the cost of the lock hardware itself. Understanding this breakdown gives you a clear picture of what you're paying for. For a standard lock change in Crawley, you can typically expect the total cost to be between £80 and £250.

At SaveMeLocksmith, we believe in transparent pricing. That’s why we have a strict No Call-Out Fee policy. You only pay for the work we do and the parts we supply, never just for our arrival. This is our guarantee. Paying for a professional ensures the job is done right, securing your property and giving you total peace of mind.

Standard Locksmith Labour Rates in the UK

The expertise of a qualified locksmith is the first part of your cost. In the UK, the average hourly rate for a locksmith is typically between £65 - £95 per hour. The good news is that most straightforward lock changes are completed efficiently, often within the first hour. Your labour charge covers not just time, but also the technician's skill, specialist tools, and our guarantee on all workmanship. Please note that emergency or out-of-hours services may have a different labour rate.

The Price of the Lock Itself: Hardware Costs

The second part of the cost is the physical lock. Hardware prices vary significantly, from around £20 for a basic cylinder lock to over £150 for a high-security, British Standard (BS3621) mortice lock. The price depends heavily on the brand, security rating, and the complexity of the different types of lock mechanisms involved. We only supply and fit high-quality, insurance-compliant locks from trusted brands to ensure your home is properly secured. Our local Crawley locksmith will always recommend the right lock for your specific door and budget, ensuring you get the best protection without overspending.

Cost by Lock Type: From Standard Cylinders to High-Security uPVC Mechanisms

The type of lock on your door is the single biggest factor in determining the final cost. Not all locks are built the same, and the price directly reflects their security features. Your door material-be it uPVC, wood, or composite-often dictates the kind of lock you need. Understanding these differences is key to answering the question of how much to change locks effectively. It's about finding the right balance between your budget and the level of protection your Crawley home deserves.

Euro Cylinder Locks Cost (Common on uPVC Doors)

Found on most uPVC and composite doors, Euro cylinders are common and come in two main security levels. We strongly recommend an anti-snap cylinder; it's a vital upgrade that protects against 'lock snapping,' a common and alarmingly fast break-in method.

• Standard Euro Cylinder (Part Only): £20 - £45
• Anti-Snap High-Security Cylinder (Part Only): £50 - £90
• Total Job Cost (Supplied & Fitted): £85 - £160

Mortice Locks Cost (Common on Wooden Doors)

Typically fitted to wooden doors, these locks are embedded into the door itself for strength. For external doors, a BS3621 standard lock is essential. This kite mark signifies it has been tested against common attacks like drilling and picking, and it's a requirement for most home insurance policies. Fitting locks that meet standards recommended by the official UK police security initiative is non-negotiable for robust home security.

• 3-Lever Mortice Lock (Part Only): £25 - £50 (Best for internal doors)
• 5-Lever BS3621 Mortice Lock (Part Only): £40 - £80 (Insurance approved for external doors)
• Total Job Cost (Supplied & Fitted): £110 - £200

uPVC Multipoint Lock Mechanisms Cost

This isn't just the keyhole; it's the entire metal strip running down your door with multiple hooks and bolts. If this mechanism fails, the whole unit needs replacing. This is a more complex job requiring precise alignment, so labour time is longer. The total cost to replace a full uPVC mechanism typically falls between £180 - £350, sometimes more for specialist systems.

Smart Lock Installation Cost

Smart locks offer keyless entry and remote access, but this technology comes at a premium. The hardware itself is a significant investment. Installation is also more involved than a simple mechanical lock, requiring setup, calibration, and app configuration. Due to this added complexity, expect the total installed cost to be higher.

• Smart Lock Hardware (Part Only): £150 - £400+
• Total Job Cost (Supplied & Fitted): £250 - £500+

Key Factors That Influence the Final Price of a Lock Change

When you're trying to figure out how much to change locks, the type of lock itself is a major part of the cost. But it’s not the whole story. Several other critical factors influence your final bill, and understanding them helps you get a clear, accurate quote from the start. A professional, local locksmith will always be transparent about these variables, ensuring you know the price before any work begins. No surprises, just secure solutions.

Time of Day: Emergency vs. Scheduled Appointments

Your security can't wait, but the time of your call does affect the price. A standard, pre-booked appointment during weekday business hours (e.g., 9am-5pm) will always be the most cost-effective option. However, if you need a locksmith urgently in the evening, over a weekend, or on a bank holiday, you should expect a higher labour rate for an out-of-hours service. This fee covers the immediate, prioritised response. Always confirm any emergency or out-of-hours charges when you call.

Number of Locks to Be Changed

It is far more efficient to change multiple locks in a single visit than to schedule separate jobs. If you've just moved into a new Crawley home, we strongly recommend changing all external door locks for your peace of mind. Many locksmiths offer a reduced rate for each additional lock changed during the same visit. Don't hesitate to ask about package deals if you need three or more locks replaced-it can significantly lower the overall cost per lock.

Complexity of the Job

Not all lock changes are created equal. The complexity of the task directly impacts the labour time and, therefore, the final price. A simple swap of a standard Euro cylinder on a wooden front door can be done very quickly. In contrast, replacing a full multi-point locking mechanism inside a uPVC door is a more intricate and time-consuming job. If your existing lock is damaged, seized, or has a key snapped inside, extra time and skill will be needed to remove it without damaging your door. A reliable technician will assess the situation upon arrival and inform you of any complications before starting work.

When to Change Locks vs. Re-Keying: Making the Cost-Effective Choice

When you're concerned about your property's security, your first thought might be about how much to change locks entirely. But a full replacement isn't always necessary. In many situations, re-keying your existing locks is a faster, equally secure, and more affordable solution to regain control over who has access to your Crawley home.

An experienced locksmith can assess your current hardware and provide honest advice. The right choice depends on the condition of your locks and your specific security needs.

What is Re-keying a Lock?

Re-keying is a precise process where a locksmith alters the inner workings of your lock cylinder. We change the configuration of the internal pins and springs without replacing the entire lock mechanism on your door. Once complete, the old keys will no longer turn the lock. We issue you a brand-new set of keys, instantly securing your property against any old, lost, or unreturned keys.

When Re-keying is the Smart Option

Choosing to re-key can save you significant money compared to the cost of a full replacement. It's the ideal choice in several common scenarios:

• You've lost a key: If the lock itself is in perfect working order, there's no need to replace it. A simple re-key ensures the lost key is useless.
• Moving into a new home: You don't know who has copies of the old keys. Re-keying provides immediate peace of mind.
• After a tenant leaves: For landlords in Crawley, re-keying is a fast and cost-effective way to secure the property for the next occupant.
• Convenience: We can re-key multiple compatible locks to work with a single key, reducing the clutter on your keychain.

When You MUST Replace the Entire Lock

Your safety is the top priority. While re-keying is efficient, there are times when a complete lock change is non-negotiable for your security. Full replacement is essential if:

• The lock is damaged or worn out: A malfunctioning lock is a security risk. If it's sticking, loose, or rusted, it needs to be replaced.
• You want a security upgrade: To move from a basic cylinder to a high-security, anti-snap, or British Standard (BS3621) lock, a full replacement is required.
• The lock is not re-keyable: Some older or cheaper models are not designed to be re-keyed and must be replaced.

How to Avoid Hidden Fees and Get a Fair, Transparent Quote

Your family’s security is not something to gamble on. When you need to change your locks, you deserve a fair, honest price without any nasty surprises. Unfortunately, some national call centres and rogue traders can add unexpected costs to your final bill, turning a stressful situation into an expensive one. Knowing the right questions to ask is your best defence.

At Save Me Locksmith, we believe in 100% transparency. The price we quote is the price you pay. Here’s how you can ensure you’re getting a fair deal, every time.

The 'No Call-Out Fee' Promise

A 'call-out fee' is a charge some companies levy just for showing up at your property, before any work even begins. We think that’s unfair. That’s why we have a simple promise: we never charge a call-out fee. Day or night, you only pay for the specific labour and lock parts that you have agreed to. Before hiring anyone, always ask them directly: "Do you charge a call-out fee?" The answer should be a straight "no."

Questions to Ask for a Clear Quote

To get an accurate picture of how much to change locks, you need to be specific. A professional locksmith should be able to answer these questions clearly over the phone. Use this checklist to protect yourself from hidden costs:

• Is the price you are quoting inclusive of VAT?
• What is your hourly labour rate?
• Can you provide an estimated cost for the new lock part itself?
• Are there any extra charges for evening, weekend, or bank holiday appointments?

Why a Local Crawley Locksmith Offers More Transparency

When you call a large national company, you’re often speaking to a call centre operator who then subcontracts the job. With a local, independent locksmith, you speak directly to the expert. Our reputation in the Crawley community is built on trust and reliability, not hidden charges. We provide a personal, accountable service because our name depends on it. You get clear answers and a direct line to the person securing your home.

Secure Your Home Without the Price Shock

Frequently Asked Questions

Is it cheaper to buy my own locks and just hire a locksmith for installation?

This can be a false economy. You risk buying an incorrect or low-quality lock that our locksmiths cannot guarantee. Our prices include sourcing and fitting the right high-security lock for your specific door, ensuring the job is done correctly and your home is secure. The small potential saving isn't worth the risk when it comes to protecting your Crawley home and family.

How long does it take a locksmith to change a standard door lock?

Changing a standard door lock is a fast process for our experienced technicians. A typical Euro cylinder or rim cylinder (Yale lock) replacement usually takes just 20-30 minutes. More complex mortice lock installations might take closer to 45 minutes. We work quickly and efficiently to secure your property with minimal disruption, arriving with all the necessary parts to complete the job in one visit.

I've just moved into a new house. Do I really need to change the locks?

Yes, absolutely. You have no way of knowing who still holds a key from the previous owners - from neighbours and cleaners to family members. Changing the locks is the only way to guarantee you have full control over who can access your new home. It’s a critical first step in securing your property and provides immediate peace of mind for your family. Don’t take any chances with your safety.

Are your locksmiths DBS checked and insured?

Yes. Your safety is our number one priority. Every Save Me Locksmith technician is fully insured and has passed a rigorous DBS (Disclosure and Barring Service) check. This means you can have complete confidence that the professional entering your home is vetted, trustworthy, and highly skilled. We are committed to providing a secure and reliable service you can depend on, 24/7.

What is a BS3621 lock and why does my insurance company require it?

A BS3621 lock is one that meets the British Standard for thief-resistance, tested against attacks like drilling and picking. Many UK home insurance providers mandate these locks on all external doors. If you don't have them, your policy could be void in the event of a burglary. When budgeting for how much to change locks, ensuring they are BS3621 compliant is essential to keep your policy valid and your home truly secure.

Can you change the locks on a garage or patio door?

Of course. We secure all entry points to your property, not just the front door. Our locksmiths are experts in changing and upgrading locks on uPVC patio doors, French doors, and garage doors. These are often vulnerable areas targeted by intruders. We can assess your entire property's security and ensure every potential access point is fitted with a high-quality, appropriate lock to keep you safe.

Is it more expensive to change a lock after a burglary?

The basic cost of the lock and labour doesn't change. However, the overall job can be more expensive. A forced entry often damages the door, frame, or the internal mechanism, which requires additional repairs or replacement parts. This extra work will affect the final price. Understanding how much to change locks proactively is always more affordable than dealing with the damage and cost after a break-in.
