Sounds like the key fob is going bad and needs replaced.

please go to the alarm or dealer shop to replace or re program

Replace the battery, and when the fob is open check the micro switch for pop, coffee contamination it may be sticking. and the key operation is normal,only the driver side gets open.

Take the key apart, replace the battery. The car needs to relearn the key, so stick it in the ignition, turn the car to the "on" setting without starting, press the unlock button on the fob. Thats it!

Key fob has a battery, may be dead.After battery replcement, has to be reprogramed. Not sure how to do it on this vehicle, may have to go to dealer and be reprogramed with a scantool

The fob is infamous for its battery life. It gets drained so quickly that there happens to be a little later when the fob is very close to the door lock, ignition & unnecessary triggers the alarm due to low reception as the battery of the fobs discharges very fast, depending on the model, which has a certain virtual sheild(STARTRECK type) which is triggered by the fobs strength of the signal(radi waves).

Why not try a new set of batteries for your fob?? .................................sodeep

Yes, insure that you have power to the trunk lock inside trunk, If not could be lose/broken wire or shot fuse. I am sure the key fob does work for the doors? If not have key fob battery replaced. Also, a quick check on power to trunk lock, check to see if have remote power button inside car, if it works power is good. Defective key fob would then be indicated.

Hi there,
Try adding a little WD40 to the lock itself. Use your hands to lock and unlock it to get the oil to spread. Put a little oil on the key, then put it into the lock. Use your hand and key to move it through the lock and unlock stages. I hope that this is some help to you. Good luck and let me know. Have a great night.~MWD
