A broken car key can mean anything from a cracked flip-key case to a blade snapped clean off in the ignition. Whatever the damage, Mobile Auto Locksmith Hamilton can assess, repair, or replace your key on site — bringing the tools and parts to wherever the vehicle is. Most broken key jobs are resolved in a single mobile visit without towing or a dealership appointment. Damaged car key repair covers cracked cases, snapped blades and worn buttons — the kind of car key fixing most people assume needs a dealer.
“Locked my keys in the boot at the supermarket with groceries melting inside. He arrived in 25 minutes, had the car open without a mark on it, and was polite and professional throughout. Highly recommend.”
Car key damage takes many forms. Understanding what type of damage you have helps us bring the right equipment:
This depends on the damage. We always assess first and give you options.
In some cases, particularly cracked cases or damaged flip-key pivots, we can rebuild the key using a new housing with the original blade and chip. This is cheaper than a full replacement because no new programming is required — the chip is already coded to your vehicle.
In other cases — broken blades, severely worn key shanks, or failed transponder chips — a full replacement is more appropriate. We will always tell you which option makes more sense before any work begins.
We start by examining the key and the lock or ignition (where accessible) to understand the full extent of the problem. If the blade is snapped, we check whether any fragment remains in the lock — this needs to be extracted before a new key can be used.
If repair is viable, we fit the old chip into a new housing or rebuild the flip mechanism. If replacement is needed, we program a new key to the vehicle and cut a blade. In either case, we test fully before we leave.
A customer in Te Rapa called us after the plastic housing on her 2017 Mazda CX-5 flip key split in two. The blade and transponder chip were both intact but the two halves of the key were held together with sellotape.
We arrived, examined the chip and blade, confirmed both were undamaged, and fitted them into a new CX-5 flip-key housing. No reprogramming was needed because the chip was original. The repair took 20 minutes and cost her less than a quarter of a full key replacement. She drove away with a solid, properly cased key.
Call us as soon as you notice key damage — do not wait until the key fails completely. If the blade is cracked, a repair now is far cheaper than an emergency replacement after it snaps off in the ignition. If the case is cracked and the chip is exposed, the chip can be damaged by moisture or physical impact.
If the key has already broken off inside the lock or ignition, stop trying to use the lock — call us first. Our Broken Key Extraction service addresses that specific scenario.

Common questions
Often yes — if the transponder chip is intact, we can move it into a new housing and save you the cost of reprogramming. We assess the damage first and give you repair vs replacement options.
