Top tips
Hiring a locksmith, without the regret.
Four moves that separate a smooth job from a nightmare.
Microswitch Failure
Often the lock is fine, but a tiny 50p switch in the handle has failed; a pro will spot this and save you buying a whole lock.
Broken Wiring Loom
Constant opening and closing can snap wires in the rubber "bellows" between the car body and the boot lid.
Incorrect Coding
Aftermarket locks sometimes fail to talk to the car’s ECU, meaning the boot won't pop on the remote.
Trim Damage
Using the wrong tools to pry off plastic panels often snaps the "one-use" clips, leading to annoying rattles while driving.
Costs & timeline
