Cost Factors of Getting Your Locks Changed

A variety of factors can affect the cost of a lock changing job, as well as increasing the amount of time it takes to be completed. Below is a general outline of the different cost factors that you’ll occur when changing your locks.

Emergency Call-out

Emergency call-out charges can massively impact the amount you spend on changing your locks. If you’re ever in a situation where you’re locked out of your house, or your lock breaks and you’re stuck, then you’ll need to call an emergency locksmith to sort the job.

Normal working hours which include Monday to Friday from 9-5 and can cost about £50 for a call-out charge. However, if you call during the hours of 6pm to 8 am, then their call-out charge can raise itself to £100 due to inconvenience and personal time.


The material costs include whichever lock choice is suited for your door. As to be expected, a budget lock cylinder will be cheaper starting at £50, whereas a better quality and secure lock cylinder will be more expensive, starting at £150.

Although it may seem easier to go for the budget option, a higher quality lock will serve you better in the long run and will help you avoid potential repair and maintenance costs.

Size of Job

The size of each job will change depending on how many locks need changing and the severity of the issue, e.g. key broken inside or lock being damaged. A standard lock changing job for several doors within your house can take between 2-3 hours for around £50 for the first hour, and an extra £25 for every extra hour.

However, if you’ve rang for an emergency locksmith, then they may not have the right materials or parts for you and will take an extra day or two to order them in.

What's Involved in Getting Your Locks Changed?

Changing your locks is usually a simple and stress-free job for any professional locksmith.

Changing Lock

Next, they will fit the new lock and deadbolt, installing the mechanism for the lock before turning the assembly plate, so it fits to the top. Next, they will twist the doorknob to view the holes in the bolt, fastening the key assembly securely.

Secure and Test

For a regular cylinder lock, you’ll need a Phillips head and flathead screwdriver, and an Allen wrench. Starting by removing the screws and spindle with both screwdrivers, then popping the cylinder out with your Allen wrench.

Hiring a Locksmith Checklist
