What is the Tailgate Locking Assembly all about?

A tonneau cover can be installed to cover your possessions in the truck bed, and a tailgate locking assembly can be used to lock the tailgate closed. Manufacturers may use a manual key-operated lock, power locking tailgate, or no locking device at all. When a tailgate lock is in place, there are mechanical components that firmly latch the tailgate handle. When the tailgate locking assembly is faulty, the tailgate lock cylinder with either not turn, or will turn without changing the lock position. If a power tailgate locking assembly is faulty, pressing the lock or unlock function will not change the lock position either.

Keep in mind:

The tailgate locking assembly can be mechanically operated with a key, opened by pushing a button on the car’s inside, or accessed remotely by an incorporated electronic actuator.

How it's done:

The tailgate is lifted and inside cover is removed for access
The defective tailgate locking assembly is removed
The new tailgate locking assembly is installed
The tailgate inside cover is reinstalled
The rear tailgate is opened and closed to check locking assembly operation

Our recommendation:

Mechanical or key-operated tailgate locks can and should be lubricated every service interval to prevent corrosion and seizing. The lock should last the lifetime of your vehicle if properly lubricated and cleaned. If your liftgate locking assembly is not working as it should, have one of our expert mechanics inspect and repair it.

What common symptoms indicate you may need to replace the Tailgate Locking Assembly?

Tailgate lock cylinder will not turn
Tailgate lock does not latch in place when the cylinder is locked
Power lock control for the tailgate makes a buzzing sound but doesn’t lock (or unlock) the latch

How important is this service?

As it is not a critical component to your vehicle’s operation, the tailgate locking assembly does not have to be repaired until you are prepared to do it. The contents of your truck box will not be secured until it is fixed.

Fast and easy service at your home or office
