Newbie 993 Owner Confused about the Keys

[wgwollet]

Hello

Just bought a 993 C2 6 speed.
The keys are switch blade style, but the previous owner tells me you must lock then unlock the car to release the immobilizer, but to me it’s a POS.

What options do I have, the manual does not say much.

I have to do that as well if you let the car sit unlocked for several mins. The immobilizer will activate but the doors will remain unlocked. At that point I have to lock and unlock the car in order to start it. Sometimes I forget to do that and try to start the car. At that point you can simply press the lock button on the key pad (while the key is still in the ignition) and then press the lock button once more to deactivate. Then it will start.

I have a 95 that was the immobilized version. Drove me crazy compared to the earlier 95 non immobilized car. They CAN be bypassed though. You must re-chip your ECU with a non immobilizer chip ( I went with a Steve Wong performance chip) and change out a relay. If you’ve got a 95. It’s plug n play. 96 and above chips are soldered in. Still doable though... This will only disable the immobilized portion of your alarm. Doors still lock. Pin lights still come on. Etc.

If locked, unlock with key fob, get in and start the car.
If unlocked, get in turn the key till the dash lights are on, look at the red led on the top of the door and press the fob button, two flashes and start the car.
If the key is left in the ignition after disarming, restart without using the fob.
If you stall while driving, turn key to restart without using the fob.

Check Pelican, they sell fob cases and key heads to change to a fob. You can use the guts of the flip key for both.
Have fun with your new 993

This used to bother me as well and I got used to doing the lock & unlock maneuver before trying to start. Then I figured out that you need to have the key turned to "on" while pushing the button. I was turning it back off. Now I've trained myself to do the following:

Always insert the key with the top (rounded) side to the left - towards the driver door. Then turn it 90 degrees to "on." This puts the soft button facing up. One push of that button - then start - works every time.

I ditched my crappy switchblade keys for the Pelican solution. Haven’t missed them since.

Newbie here as well and couldn't consistently get this right. Now I just double up the process (lock and unlock again) before getting into the car.

Just had to explain this to my detailer for my '97 993 Turbo S. This was the "Porsche Drive Block" immobilizer system. Freaks you out a little when you first get a 993, but I assure you it becomes pretty routine after a short while whether you have the switchblades or convert to fob.
