I cannot get my trunk to pop open at all. FOB button is not working and neither is the button in the car. Sucks! $250 deductible to take it in for warranty fix. What can I do to avoid that?

 

Isn’t there a valet button in the glovebox? Maybe check that out

 

Did you read the reply in your earlier post?

I checked that and that is just to keep the valet out of the trunk. If it's not pushed in it inhibits the FOB and button on the driver's side from opening the trunk. The only way I can get it to open is to open the arm rest access to the trunk and use a stick to engage the emergency release actuator on the inside of the trunk lid. It opens then but once I close it again neither the FOB or the button on the driver's side will open the trunk.

 

By chance, have you recently had the glove box replaced (for ZLZ warranty) or any other work concerning the valet button? If the connector/wires for this are disconnected/broken, it will not allow the trunk to be opened electrically. If this is the case, not sure if the physical key will open it either. I experienced this when the dealer installed my new glove box assembly two months ago.

 

This is only a guess. It could be something else too.

The electronic trunk lock mechanism is pretty common to fail on these. You can often get the fob to function again for a day by disconnecting the negative battery cable for 10 minutes then reconnecting it.

I'm impressed you could pull that emergency release with enough force to open the trunk. The outside of the trunk also has a key slot for your physical key within the fob to open the trunk. In my case the key slot did not function.

In my case I got the trunk to open using the "disconnect / reconnect battery" method. Then I replaced the lock actuator. It's a $250-300 part.
