How do I get my key out of the trunk lock - it is stuck in the lock. Help please?

Might try some graphite lock lube in the keyhole.

remove the back seat. and try it from inside

at trunk button override and jump switch if dont work have to make way to get through at back seat

If you hear the sound of the electric latch switch, then it's working but stuck somehow. Just put the key in the switch and turn it to the right and then pull up the trunk or ask someone to help you. it will open. I tried it today and it opened with me. It was stuck from inside by some kind of a broken plastic pieces. Just removed it and now it's working fine. good luck

if you open the arm rest in the back seat then open the acess door to the trunk should be a pull cable to open trunk just inside

auto trunk latch is stuck down try putting key in the lock hole and opening the trunk switch maybe it will rise.

Wrong key for the trunk is my first guess.

The lock latch is held by a spring to be in Normal Close position. It it is in open position then there is 2 possible root causes: 1- The cable pulling the latch to open gets stuck. 2- The spring broken or out of its position. Hope this can help to fix it.

Try spraying the inner portion of it with some WD40 or similar lubricant. It sounds like something must be stuck. After you spray it, keep working the key and pushing the remote until you get some results. Good luck. Let me know how you make out.

the dealer gave you a ignition key, instead of valet key.
valet key should open the driver door and ignition. nothing else. if the key can't ope the door. try the trunk. if it open the trunk, the it is a wrong key.
