[MARCN7798]

hi, can anybody help me with a little problem i have, i cant open the doors with the remote, replaced battery still no joy any ideas??
the car is a 986

sounds like you may need a new fob which unfortunatly is dealer only due to security codes for ecu's cost around £180 from dealer

not sure this helps as i have a 987 but if i don't use the key for over two weeks i have to use it in the lock first to pair up the remote function again otherwise the car ignores the remote.

MARCN7798, The remote control is indeed a weak point with these cars - there are lots of remedies you will hear on this site about resyncronisation and wizardry but sadly most do not work.
Try turning the battery in the remote the opposite way around - it doesnt reverse the polarity all it actually does is make the positive and negative connections on the circuit board one complete circuit - this has the effect of zeroing the electronics - then simply put the battery the correct way around and try again - I assume you have checked that the battery is "Good"

You will most likely need to get a new remote - about £140 with the programming, takes 15 minutes and good for a few years

Hi mate,
I've had the same issue on my 986 S. Unlike the 987's, the 986 dissasociate themsleves with the key after 5 days. You need to manually open the car with the key then the two alarms sound and you reset it by pressing the main button on the key.
It has happened to me once before inside the 5 days and I simply had to open the car with the key, let the alarm sound and then reset it with the button.
Hope you get into it soon!!
Cheers,
Lee

The car doesn't diassociate itself from the key.

Simply put, to save the battery after 5 days it turns off the radio sensors that are "looking" for the remote.

You don't need to let the alarm go off:

Put key in door.
Turn it to unlock the car and "wake" up the systems.
Do not open door.
Press "lock/unlock" button on key to turn alarm off.

Carry on as normal.

When I bought my 986 it had 2 keys one didn't work electronically the other did. Both worked manually. The working one became intermittent and gave up eventually. There was nothing for it but to buy new ones at the Porsche centre and get them to program the ecu. If I remember correctly they have a list of valid keys in the ecu and mine had a good long list in that they cleared. So it has got through a few keys in its life.

Also it is worth noting that if you take the battery out then you have about 30 seconds to put the new one in otherwise you need to go to the OPC for them to progam up the key again.

Doesnt matter how long the battery is out as the code is on a chip within the circuit board, nothing can be lost
