Porsche 2000 911 Carrera. Key fob problem

Boxster key remotes are reprogrammed by put the key in the ignition turning the ignition on but not starting the car, then hold down the door lock on the remote for like 5 sec. Ta da... She's reprogrammed.

I don't know about Porsche but you can get a key fob battery to fit most fobs at Wal-mart or any car parts store.

There is a small depression in the side of the key. Insert a very small screwdriver into the depression and pry the top and bottom of the key loose. The battery is in the center, just pull it out (or pry it a bit with your little screwdriver) and replace. The top just snaps back on.

hello there
i think you should call local dealer -they need to prgram your key

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.

unlock the door then press the lock button on remote and hold down for 20/30 secs.manual does say hold button.....

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

i presume little led in fob flashes when button pressed. Key needs to be initialised. Put key in door lock or ignition barrel and press unlock button watching led on dash, this should flash. remove key from lock, remote should now work

Hi,

Maybe you can try this procedure to resyn your key.
Initialization Procedure.

1. Open central locking system using the car key.
2. Get into the car and close all doors.
3. Using the car key, switch the ignition lock briefly to position "1" and then switch off again. (Please do this switching within 5 seconds or otherwise the system is not ready for initialization.
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.

I have the same problem with my 1995 Porsche 911. I was quoted $260 for the key fob and $70 to program it. Sheesh!
