As you'll see from the table above, the cost to replace an uPVC door lock mechanism near you will vary depending on the type of lock you need and if it's installed during standard working hours.
To get a better steer on the costs involved, let's look into it one service and lock at a time:
Typical uPVC lock replacement costs
Locksmith services
The average locksmith charges for uPVC locks are around £50 - £95 per hour, averaging at **£75 per hour. If you wish to get your uPVC door lock changed, that takes around one to three hours generally, depending on various factors
If you want your door locks changed out-of-hours, this will cost you more. Most locksmiths' hourly rates for such a situation would be between £75 - £125
But when working out how much a uPVC lock replacement will cost you, it's not just the locksmith's labour fee you need to account for. You'll also need to factor in the cost of the lock itself. That's up next.
Standard euro cylinder locks
Euro cylinder locks are one of the most common lock mechanisms you'll see in uPVC doors
It's one of the cheapest to install
The lock is fitted within the handle and is often used with multi-point locking systems
The same key could unlock the front and back doors of your home
The approximate cost to have a professional locksmith replace a standard Euro cylinder lock on an uPVC door is between £75 - £125.
Anti-snap euro cylinder locks
While very similar to euro cylinder locks, these locks have one key difference: their security level
They have a much higher security rating because they cannot be picked
They are tested against lock snapping and lock bumping
The cost for a locksmith to replace an anti-snap euro cylinder lock is between £100 - £150.
Factors influencing costs
It is difficult to calculate the exact uPVC door lock replacement cost. That's because many factors need to be taken into account, including:
Time of day
You're looking at paying a premium for out-of-hours locksmith services. Costs tend to be 25% extra for middle-of-the-night or weekend jobs.
Expect to pay on average £100per hour rather than the standard £75hourly fee.
Type of lock
Due to different levels of security and durability, your uPVC lock replacement cost may be higher depending on which brand you choose.
For instance, if you're replacing an anti-snap cylinder, you'll pay an average of £125.This is more than a standard euro cylinder, which costs on average £100. This is because anti-snap locks are more expensive to buy due to the additional security mechanisms within the lock.
Labour and travel costs
Is it the dead of night, and the only available professional locksmith you can find is a twenty-minute drive away? This will cost you more as your locksmith needs to account for travel time, mileage, and labour costs. This soon mounts up, but it's standard practice for locksmiths to quote for these additional factors.
Cost comparison by lock type
As we've explored above, euro cylinder and anti-snap locks are the most commonly used for uPVC doors. However, there are other options, such as more sophisticated multi-point locking mechanisms, though these tend to cost more.
For instance, the cost to replace an uPVC door lock with a full multipoint lock strip could be in the region of £120 - £300. This is substantially more than the cost of a standard euro cylinder lock, which costs between £75 - £125.
It's also worth noting some specialist lock parts may not be as readily available. In such cases, it may be necessary to board up broken windows and doors until repairs can be made. This will mean additional costs but is essential to keep your home safe.

Other factors that affect uPVC door lock replacement costs
Along with the factors listed above, there are other circumstances which could impact your uPVC door lock replacement cost. They include:
British standard locks
Certified by the British Standards Institute (BSI), which undertakes rigorous testing as a standard to assess new locks, British Standard locks will be stronger and more secure than non-British Standard locks. However, they can also work out more expensive than standard euro cylinders.
Time-sensitive jobs and extra fees
If you are locked out and need a locksmith to help you gain entry, this will incur a charge of approximately £75 - £150.
In certain circumstances (e.g. if you require emergency assistance and the only locksmith available has to travel a large distance), you will be charged extra for the distance they travel.
Complex jobs
If you're looking to change all the locks at your home, the cost will be significantly more.
For this, you're looking at an average of £500per home, but for larger homes, this could be more.
Gearbox replacement
If you're lucky, it might just be that the lock's gearbox needs to be replaced rather than the whole locking mechanism.
The door gearbox is a part of the central locking mechanism of an uPVC door and interacts directly with the handle, spindle, and key cylinder.
The average uPVC door gearbox replacement cost is an average of £90. This is slightly less than the cost of a standard euro cylinder lock.
Repairs to damaged doors and windows
Have you experienced a break-in or attempted break-in to your home? Replacing locks while repairing any damage to your doors or windows goes hand-in-hand.
Your locksmith may be able to help with boarding up broken windows and doors until repairs can be made. This will be an additional cost but is essential to keep your home safe.

Tips to extend the life of your uPVC door locks
Generally speaking, uPVC door locks are super hardwearing. However, how often you use the door and the conditions of where it is can impact the lifespan of your door. For instance, it's less likely to rust if it's located beneath a porch and sheltered from the rain.
Here are a few maintenance tips you can do to keep your lock working smoothly and lasting longer. They are:
Cleaning – Regularly clean the lock, handles, and hinges with mild detergent and water to remove dust and grime
Lubrication – Apply a small amount of silicone-based lubricant or graphite powder to the hinges and lock mechanism to stop your lock from sticking
Alignment – Check that the door and frame are aligned and adjust the hinges if necessary
However, if there are visible signs of rusting or the lock is continually sticking and temperamental, it's probably time to look at replacing your lock.
Working out uPVC door lock replacement costs
As well as the costs for labour and the lock itself, it is important to budget for any additional costs that may arise when replacing your locks.
These include:
Gaining access if locked out (depending on the ease of access)
Replacing broken windows or doors that may get damaged
Broken or snapped keys that are inside your door lock
If you have been burgled, you may choose to replace all the locks at a property (this costs around £400 – £600 depending on the locks used and amount of locks)
In certain circumstances, it may be possible to replace lost keys without changing your locks. In this case, you will be charged for the new keys and any call-out fees.
