My Porsche Key fob no longer unlocks the doors

My Porsche Key fob (05 911 C2S) no longer unlocks the doors wirelessly but does work on the ignition. I tried unlocking door manually then hitting unlock/lock button of fob and nothing (per the manual) everything else works fine.... any suggestions?

Insert key into door barrel or ignition lock and turn key, whilst doing this press the unlock/lock button, the led on the dash should flash to indicate this has initialised the key to the car, then remove key and test operation of remote. If this fails then a new remote plus coding to the car by your dealership is needed

Doors unlock by themself


Assuming you mean door unlocks while parked? Toyota will not allow door to be locked using the remote control while key is in the ignition or if you with a wireless proximity key (now referred to as a FOB), while the wireless key is still in the car. If these are not the case, you may need to check out the sensor in the ignition or if using a FOB, the computer interface between the FOB circuit and the door lock.

1999 porsche 996 replaced key fob battery disconnected battery now trunk releses are locked and cant access battery.How do you open frt trunk manually


Assuming the car battery is ok (if not, buy a male to male cigarette lighter at the auto store and connect to another car until charged enough to unlock the doors...but don't try to crank the ignition!). The trunks won't open if the battery went dead with the alarm set because arming the alarm physically locks the releases.

Sounds like the key code is switched off because you replaced the key fob battery. Try unlocking the car manual with the key in the door lock. Then switch the ignition on to reactive the keyless entry. If this does not work, you might also try pressing the fob unlock button with the key in the door lock until the dash led flashes.

Key fob not working


does the led on remote flash when pressed, if so try to initialise remote by inserting key in door barrel or ignition lockthen turning key, whilst doing this press and hold lock/unlock button. the led on dash should flash to show the key has been initialised, then remove key and test operation. If none of this works then a new remote and coding to car is needed by your nearest dealership

Maybe you can try this procedure to resyn your key.

4. At the remote control key. Press the "OPEN" key (->) and keep holding.
5. When holding the "OPEN" key, press the "LOCK" button three time.
6. After pressing the "LOCK" button 3 times, release the "OPEN" button.
7. If the initialization process is sucessful, the door will lock and unlock immediately to confirm the process.
