GTA Lockman Mobile Locksmith Services replaces car keys and fobs across Toronto and the GTA. We bring key cutting machines and programming equipment to the vehicle, so you do not need to tow it to a dealership.
We work on standard keys, transponder chip keys, remote head keys, flip keys and proximity fobs for push-button start. Tell us the make, model and year when you call and we confirm what is possible for your vehicle.
A spare costs far less than replacing the only key after it is lost. When every key is gone, the vehicle's computer has to be accessed to add a new one, which takes more time. If you are down to one key, getting a spare now is the cheaper option. See spare keys and duplication.

We can make a new key even when no key is left. The key is cut from the lock or the key code and then programmed to the vehicle. Old keys can be removed from the vehicle's memory so a lost key no longer starts the car. See key codes and key numbers.
A key that will not turn in the ignition is often a worn ignition cylinder rather than a bad key. We repair or replace ignition cylinders and door locks on many makes.
For keys locked inside the vehicle, see car lockout service. For brand-specific details, see Cadillac key replacement and Mitsubishi key replacement.
See car key types explained for how each one works.
We also replace motorcycle keys, and help with keys for rental trucks such as U-Haul. When a key has been lost or stolen, we can remove it from the vehicle's memory so it no longer starts the car.
Call (647) 955-3277 or use the contact form and tell us the address and the make, model and year. We confirm the price and give you an arrival estimate before booking, and the technician explains the work on site before starting.
