Tailgate lock assist will not work - 525 BMW Cars & Trucks

Replacing the tailgate lock on a Honda Jazz 2014 involves several steps. Here's a general outline of the process:

1. Open the tailgate: Begin by opening the tailgate and locating the lock mechanism.
2. Remove the trim panel: You will need to remove the trim panel that covers the tailgate lock mechanism. This may require the use of a trim tool or a screwdriver, depending on the exact model of your Honda Jazz.
3. Disconnect the electrical connections: After removing the trim panel, you will need to disconnect any electrical connections that are attached to the lock mechanism. This will likely involve disconnecting the wires from the tailgate lock switch.
4. Remove the old lock mechanism: Next, you will need to remove the old lock mechanism. This may require the use of a socket wrench or pliers, depending on the type of mechanism that is installed.
5. Install the new lock mechanism: Once the old lock mechanism has been removed, you can install the new one. Make sure that the mechanism is securely fastened and that all electrical connections are properly reattached.
6. Reinstall the trim panel: Finally, reinstall the trim panel that covers the lock mechanism.

It is important to note that this process can vary depending on the exact model of your Honda Jazz, so it is always a good idea to consult your owner's manual or a professional mechanic for specific instructions and guidance. Additionally, it is recommended that you wear protective gloves and safety glasses when working on the tailgate lock to avoid injury.

Have you tried using the key at the tail gate, ,open with the key then move then push the locking mechanism open with a screwdriver the latch close while the door/gate was open, push it back open use some force. Hope this help if is a mechanical issue and not electrical it doesn't matter .

I would have used the lock mechanism from old tailgate. has it been deadlocked?

If this is an original equipment replacement part should work just like its predeceser before the accident. Just check that everything is wel connected and in place by removing the panels and take a look inside.

Try a graphite lock lubricant. It works better than wd40

Sounds like the lock actuator in the tailgate has gone bad. I have a 1999 that had the same problem. Its about a 120 part from the chrysler dealership and involves taking the interior trim off the tailgate to repair.

First thing: Try using the key to move to the locked and then to the unlocked position. If this works, open the tailgate... This also pretty much tells you what the root cause problem is, which is a pressed-in plastic post working its way out (see below).

If no bedliner, just remove metal plate inside tailgate and actuate by hand inside to open. If bedliner, first use a small screwdriver to carefully (don't scratch paint) push in latches at either side of tailgate to open/lower tailgate (if locking/unlocking as above did not work to lower gate and gain access). Next, use two blade screwdrivers to pry out the "buttons" that hold the ends of the tailgate liner where they wrap around the sides, then remove bedliner piece and metal plate, etc.

Once you have access to inside of tailgate, you will see how the mechanism works by pulling up and down on the handle while observing. You will probably find that the slide mechism that locks and unlocks the mechanism has been allowed to move such that it cannot unlock/allow movement of the latching mechanism. This is usually the result of the pressed in plastic anchor being worn/loose. I had some success with cleaning thoroughly with alcohol or brake cleaner, allowing to dry and then using super glue to hold it firmly in all the way. Still have to hold handle up when closing gate and keep key on hand to unlock every time opening, but it was a free repair...

The lock accuator on the tailgate is bad.

I don't think you need a wiring diagram.
Jeep had alot of problems with the lock accuator in the tailgate.
