Central locking problem

[mostinpowers]

Hi Guys

Wonder if anyone can help me? I have a '99 996 cabriolet,I cannot lock or unlock my car with the remote key. It is not the battery as I have changed it. The led on both the key and the receiver unit both flash when the key is pressed but the doors do not lock/unlock. The doors lock/ unlock ok by key.

Any ideas would be gratefully received!!

Have you tried both keys (with remotes)?

If so, you likely need to find a dealer that can re-program them for you. If re-programming does not work then you will need to buy a new remote.

is it working with your dash switch?

I just wrote this and then saw this posting...

I can lock/unlock from the key and the door switch... Is that it, dealer is the only option?

I wanted to post anyway to see if anyone has any ideas about the alarm issue as well.

Thanks,

I have two issue that are some what related but not same cause I'm sure.

When I got the car a year ago the remote entry was intermittent, now it is not, it doesn't work 100% of the time. Tried the battery to no avail. I read the DIY about extending the range and I'm tempted to open up the bundle in the pillar just to try something there. Any ideas, suggestions, gotcha's out there?

Second issue, my alarm goes off randomly when I'm parked in the sun even if the windows and sunroof are cracked. I've had the same problem with Audi's and VW's. Anyone else have this issue? Can I adjust the sensitivity or is this one for the shop?

Thanks,

check the battery retaining clip on your remote, make sure it is tight.

second issue is prolly caused by a faulty interior compartment contact,,,sounds like hot temp is making it expand.

Hi yes the dash switch works fine

If it works fine with the dash switch then it has to be the key(s).

I have had the same thing with an Audi in the past.

It is possible that your key has lost synchronization with your car and can be reset by doing the following:

1. Manually unlock your car using the key

2. Open the car door (note if your alarm goes off, put your key in the ignition to stop the alarm.

3. Press the unlock button on your remote and the remote will resynchronize with your car.

Note: If you leave your car locked for more than 5 consecutive days, the car will deactive the remote receiver to reduce battery load and you will be forced to use the procedures listed above to reset it.

IF THAT DOESN'T WORK THEN TRY:

With the Audi, you had to use the lock button held down for about 30seconds maybe a bit longer up to a minute. If held within the range of the car

it would work after that time and re-synchronise itself.

OR

Use the key in the ignition and turn ignition on. Switch off, remove key, then operate key within 6 seconds of removal.

I hope one of those methods may be of use to you.

Ok thanks to everyone that gave advice on this but it appears my key is totally dead so i've ordered a new one from a Porsche specialist.

My key stopped unlocking the doors and I went through the steps above. Replacing the battery didn't work until I pressed the retaining clip (the metal part) against the battery. I guess the contact was a little loose. Thanks for the great troubleshooting tips!

thanks for the tips on this all. I was able to diagnose and correct the remote key not working on my '99 996.

symptoms i experienced were -

- light on key fob was blinking fast (obviously not battery in key fob)

- replaced battery anyway

- doors would unlock/lock by pressing on dash button (obviously nothing wrong with car electrics)

- tried the above "reset" procedures (key fob still didn't work)

- pulled key apart and pressed on battery whilst deprssing remote button (car unlocked/locked)

- tried to gently bend battery contacts in order to ensure battery was making good contact (had intermittent success)

- wedged a small piece of felt inside the key and closed the key (car now remote locks/unlocks like a charm!)

i think i will try to get a small spring to wedge in the key in place of the felt for a cleaner fix.

thanks to all for your assistance.
