Keyless Entry System
After having to replace the key fob twice in the past 3 years, due to my keyless entry not working on MY99 996 C2, I looked at going to an aftermarket keyless entry system. I ended up talking to a local auto alarm store in my area, and they installed a Viper keyless entry system, that was hooked up to the existing Porsche alarm system and has been working really well for me.. The front lights don’t flash anymore and I still don’t get an audible beep but the range of the remote is significantly better then with the Porsche key fob. No longer do I have to stand right next to the car to lock and unlock the doors. Also the cost of going this way was 2/3rds the cost of buying another keyfob and getting it programmed at the dealer. Additionally, the cost of replacing the aftermarket remote if it goes bad is it inexpensive. The down side of course is you have to carry both the key and the remote on your keychain.
Now, I have a co-worker of mine who has a MY02 996 Targa who a while back also had the same problem with his key fob not working anymore. I mentioned that I had installed an aftermarket keyless entry system and he ended up going to the same installer to have the same keyless entry installed on his Targa. For whatever reasons the aftermarket keyless entry system does not work on his car. It will work briefly when he gets out of his car and locks or unlocks the doors with the remote before the alarm firmly sets. But, when the alarm is set the remote no longer works, though the installer says he can hear the aftermarket keyless entry system clicking like it is trying to unlock or lock the doors. One thing that neither the installer or I knew was that on the 2002 cars, if you use the key to unlock the door, then open the door, that the key needs to be inserted and turned in the iginition, or the alarm goes off. I read this later while doing a search on this forum, then I confirmed it by looking at my co-workers owners manual. This is not the case on the 1999 cars, like mine.
Is it possible that this feature on the 2002 cars is the reason why the keyless entry doesn’t work? The installer says that the wiring diagrams for the alarm system on both years are the same. Therefore, he used the same wires to connect the keyless entry system.
