Anyone ever had problems with the immobiliser - I sometimes have to spend a number of goes before it beeps.

I can remeber reading somewhere that the contacts can go and need to be replaced. Any ideas on cost?

Previous posted on Porsche 968 forum.

I have the CAT 2 Porsche immobiliser that requires a flat spade type key to be inserted into a slot located adjacent to the ignition key / lock.

During the process this action can often take 2,3 or even 4 attempts before successfully achieving deactivation.

After only 2.5 years ownership, I discovered at the weekend that if of instead of reinserting the key, I simply held the key firmly in the slot and waited, the deactivation beeps took place on the next cycle.

It works for me, just a short wait and patience required.

+ the above procedure will also cause less wear over time.

My 1st post on P'heads. Have fun.

I had the same problem fixed not so long ago. I used JZ Machtech.

£100ish all in (if I remember correctly). They only needed my car for a day.

Def. worth having it fixed.

the immobiliser control unit is often sited under the floorpan and does frequently suffer from corrosion. Used to have exactly the same problem on my old 944. if you wear a tie to work then the solution is easy - just rub the key tines up and down a few times with your tie. i think it must generate a static charge to get the signal round the corroded circuit. who knows. anyway, worked for me.

oh, by the way, works best with 100% silk ties (naturally)

well blow me down - hello there!
hasten to add the tie trick was for my old red 944, not the blue S2, but glad it worked nevertheless. glad you are having fun still - ive moved to a 968 but there is still something brutally efficient about the S2 that brings fond memories
