PK3 TAMPEr MODE SYMPTOMS The vehicle doesn’t start and the info center indicates a PK3+ failure. • To exit PK3+ Tamper Mode, repair the failure in question. • Close all vehicle doors • Wait at least 3 minutes. • Then start the vehicle using a valid key. • The vehicle should start. • If the vehicle refuses to start, unplug the vehicle battery for 30 seconds, then reconnect the battery and start the vehicle again. If the circuitry is properly connected and a valid key is used, the vehicle will start.

try this to....• To exit Passlock Tamper Mode, repair the failure in question. • During the following steps, make sure the battery is fully charged (it is recommend to apply e-brake to turn off DTRL on Canadian vehicles). • Turn the vehicle ignition ON, move the key to the START position and bring it back to the ON position before the car started. • Leave the key to the ON position. The security indicator will start blinking. • After 10 minutes, the security indicator will stop blinking, turn ON solid, then turn OFF. • Turn the vehicle ignition to the OFF position, wait 15 seconds and then attempt to start the vehicle. • If the vehicle starts, wait for the security indicator to turn OFF before you turn off the engine. If the vehicle fails to start, keep the ignition ON, you are in “BAD” Tamper mode and may have to repeat the entire sequence up to 3 times which may take over 30 minutes. There’s no solution to get the vehicle out of Tamper Mode faster then waiting the required delays in each cycles.

tried the reset to get out of tamper mode like you described the security light never flasher at all just stayed on. I have disconnected the battery and put a charger on the car and will try this again tomorrow.I also removed the remote starter system thinking it may be causing the issue but the problem is still there. Hope I did not fry a computer of something. Thanks for your assistance with my issue TerryTerry

Tried the reset and still have the same issue what would my next step be? TerryTerry

Did you un-do the cut +12V wire at the PassKey3 connector when you removed the R/S and bypass module?Soldering is fun!
