What do lock installation services include?

If you’ve just moved into a new home, consider replacing its old locks and installing new ones. Whether it’s a traditional deadbolt lock or a keyless entry system, you can find a Tasker who can fit and install the best lock for your home. Below is the possible range of services that you can look forward to: 

Lock fitting

A professional locksmith can help properly fit a lock to your door or window. Remember that there are different types of locks that work best with certain kinds of doors and windows. For example, a UPVC door lock functions best with a patio door or screen door. 

Consult with your Tasker with what lock options you can choose from. Using their tools, they can fit the lock perfectly into your barrier or aperture. 

Door lock installation

Most mobile locksmiths are trained in residential lock installation and help properly install locks to your front door, patio door, and bedroom doors. If you own an office or a retail space, then your mobile locksmith can also repair, replace, and install new locks for your building or store. 

Keep in mind that replacing your locks can ensure the security of your home and prevent break-ins. 

Car lock installation

Want an upgrade on your car’s security system? Hiring a Tasker can help ease the stress of fitting and installing a brand new lock on your vehicle. Depending on what you need, your Tasker can help replace or fit a lock on your car door or trunk or even install a central locking system. 

For parents, you can also babyproof your vehicle and have your Tasker install childproof locks.

Electronic lock installation

Even the oldest or simplest homes can boast top-of-the-line security systems. With Airtasker, you can find a mobile locksmith who can install electronic locks such as keypad locks, Bluetooth locks, magnetic door locks, and more. 

Your Tasker can also smoothly install keyless entry systems, so you can move in and out of your property with ease (and without fumbling with your key chains every single time!).

High-security lock installation

High-security lock systems protect against robberies or any other method of trespassing and attack. Your mobile locksmith can help install a heavy-duty lock that can withstand picking and drilling. 

If you’re looking to upgrade the security of your property with video surveillance and alarms, consider hiring a security system installer near you.

New lock installed in door

£150

Collier's Wood, Greater London, SW19

30th Apr 2026

Wooden exterior door with a mortice lock that has been poorly installed. The lock is misaligned with the frame, the key is stiff to turn, and it often doesn’t engage properly. Likely requires repositioning or replacing the mortice lock, adjusting the strike plate, and filling previous fixing holes for a secure, properly aligned fit. Please quote for repair vs replacement (including a BS3621 lock if needed). Can update with photos tomorrow. Thanks for great offers, here are the photos which show detail of the door.

Nasser was knowledgeable about what was needed for the job, worked cleanly & efficiently doing extra elements to make sure the door closing worked smoothly. Extremely happy to have booked him.
