The back up lights are activated when you put the car in reverse. A signal is sent to the PCM (power control module), the PCM sends a serial message to the BCM (body control module). The BCM then grounds a relay in the under hood fuse center, power is sent by the relay to the rear backup lights.
So, if your back up lights are "flashing" when you use your remote, we know the circuit from the BCM all the way back to the back up lights is good.
The problem appears to be with the transmission park/neutral switch is not sending the signal to the PCM for some reason. It could be the switch or connection or wire from the transmission park/neutral switch to the PCM.
A service tech will be able to scan the ECM and determine if the switch is functioning or not.
If you wish, you can check the connections at the transmission and PCM, but they are somewhat difficult to get to.
Hope this has answered your question, let me know if there is anything further.
Regards,

anit theft is activated. It should deactivate if you close all doors and hood and open with key or fob from outside of truck.

You must have opened a door by reaching inside and opening the door when it was locked. Once locked, it msut be unlocked with key or fob so the ouside lock sensor will tell the module it was unlocked porperly. Or, you have a bad door lock sensor switch.

My Porsche Key fob no longer unlocks the doors


Insert key into door barrel or ignition lock and turn key, whilst doing this press the unlock/lock button, the led on the dash should flash to indicate this has initialised the key to the car, then remove key and test operation of remote. If this fails then a new remote plus coding to the car by your dealership is needed

'98 Saturn SL1 won't start. Alarm system behaving strangely. Have power, turn key-nothing. Then it will start for no reason. Drove it home (20 miles), shut it off and it won't start again. Changed battery...


I had this same exact problem in a family member's Saturn. If you are opening the door with the key and not using the key FOB to unlock the doors, then the security system will not allow you to start the car. You will notice when this happens that the dome light will blink and you'll hear the relay in the BCM clicking.

In order to stop the security system from doing this: Make sure the car is locked with the key fob by hitting the lock button. Then hit the unlock button on the key fob once and then once again (I do it out of habit). Then open the driver side door, put the key in and it should start no problem.

2005 key fob controls do not open locks


The key fob will have a very small opening along the seam. Use a small flat head screwdriver to prey the seam apart.
