Fortunately, replacing your locks does not have to be an expensive, drawn-out process. Most locksmiths are available any time of day and out of hours, plus they usually have a range of new locks ready to be installed.

Different types of uPVC door locks

It is easy to be confused by the multitude of locking mechanisms and structures on the market, however, there are two common locks used for uPVC doors:

Euro cylinder locks: These are very popular as they are extremely versatile, removing the cylinder is very easy and it is possible to use the same key with different cylinders for buildings with several offices.

Anti-snap euro cylinder locks: Whilst very similar to euro cylinder locks, these locks have one key difference, their security level. As they cannot be picked open and are tested against lock snapping and lock bumping, they have a much higher security rating.

When calculating the cost to replace a uPVC door lock it is important to also consider the cost of labour if hiring a locksmith. For reference, the cost of simply buying a replacement uPVC door lock is from £75 – £125 for a standard euro cylinder lock and from £100 – £150 for an anti-snap euro cylinder lock.

Door installation cost guideFactors affecting the cost of replacing a uPVC door lock

Unfortunately, it is difficult to calculate the exact cost of replacing a uPVC door lock as there are many factors that need to be taken into account, including:

The standard: British Standard locks are certified by the BSI so will be stronger and more secure than non-British Standard locks, but more costly.

Time of day: If you are locked out and urgently need your lock replacing out of hours, this will incur an extra charge of approximately £25 – £35 per hour.

Brand of lock: Due to different levels of security and durability, depending on which brand you choose the costs may be higher than the average figure from the above table.

Labour costs: The time taken by the locksmith to replace your lock. It is often possible to agree on a price beforehand based on an estimate of the time required and as such you will pay that fixed cost no matter how long it takes. Complex jobs, such as replacing all the locks in a home, will take a lot longer.

Travel: 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.

Lock type: Multi lever locks will add to the overall cost of your replacement, priced between £150 – £250.

Please note, if lock parts are not readily available, it may be necessary to board up broken windows and doors until repairs can be made. This will include additional costs but is essential to keep your home safe.

How much does it cost to change a front door lock?

With such a wide range of locks available, beyond just locks for uPVC doors, it is difficult to exactly estimate the cost of replacing a front door lock.

The cost for this will be roughly between £100 – £200, however, taking into account the factors described in the previous section you will need to adjust this price accordingly.

If you’re looking to get a patio door lock replaced instead, this usually costs £90 – £120.

Security door lock replacement cost

Security doors are designed to be extremely difficult to break through. They are heavy and usually made of steel, with very secure and complex locks. Due to this, it is vital to hire a professional locksmith who will be able to give you an accurate cost for replacing a security door lock. The labour cost for a professional locksmith will usually be between £50 – £95.

Installation of door lockAdditional door lock change 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. This can be a significant job depending on the ease of access and can cost around £75 – £150.
  • Replacing broken windows or doors that are damaged when gaining entry to your home if you are locked out.
  • Broken or snapped keys that are inside your door lock. These will need to be removed and will probably incur extra costs.
  • 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.

How long does it take to change a lock on a door?

The time taken to change door locks will vary based on the type of door you have, your existing locks, the new locks required and any damage to your door or lock that needs to be repaired. The average time taken is approximately 1 to 3 hours.
