I was helping a friend installing Viper 5901 on to his S2k... It is my third viper 5901 install on the S2000.

But the doors wont unlock, even if the alarm is disconnected, then we tried the Keyless module on another S2k its the same (won't unlock, only locks). So then I tested the relays it wont go negative for unlock it stays at 9volt not 12v or 0v any suggestion in fixing this?

I will need to double check if theres a short circuit somewhere that caused the failure of the module.

Im guessing replacing the module will be expensive, can I just replace the relays on the circuit board?

 

If you are is using a jap-spec Keyless module, they can be found cheap on yahoo japan auctions.

 

Yea have just tested all the connection according to the service manual, seems like everything is working fine except the keyless module itself...

yea seems like yahoo auction or junk yards the way to go...
