Cars and trucks require locks on doors and trunks to prevent theft. Each lock is different in its configuration and installation/removal procedure. The trunk lock is no exception. Some locks are electronic in that they are unlocked using an electronic key. These locks have a plug of wires that comes from the electronic wire harness that provides power to the lock. Some locks are simple tumbler type locks that are locked and unlocked using a metal key.
Use the crescent wrench to disconnect both battery terminals.
Open the trunk using the metal or electronic key.
Disconnect the electrical connector for the electronic lock. There is a pin connector plugged into the back of the lock that has to be disconnected by pulling it free of the female end. Only electronic locks have this feature.
Use a crescent wrench to hold the threaded lock post and another wrench to hold the larger retaining nut.
Turn the retaining nut counterclockwise and remove.
Pull the lock through the housing hole in the trunk and discard.
Insert the new electronic or key lock into the trunk housing hole.
Use one crescent wench to hold the threaded lock post in place and the other to screw the retaining nut in place by turning the nut clockwise until snug, just a turn beyond hand-tight.
Plug in the electronic lock connector to the back of the lock.
Reconnect the battery terminals using the crescent wrench to turn the retaining bolts clockwise.
