there are no PASS-LOCK hacks,

thats how key entry works as to fob -dead battery--failure

It’s most likely a broken wire in the drivers door. With constant opening and closing over the years these wires break. It’s an easy fix to someone who is handy with wiring.

It shouldn't, they are separate systems. You may need to reprogram the key fob, (If that's what you meant by "keyless") but that can only be done by dealer on that vehicle. If the passlock gives you problems, you can bypass that.

These need to be checked:

Confirm the latest ignition switch is installed per TSB 04-08-45-005D.

2. Check the BCM PWR fuse.

3. If ok, check all of the door lock and unlock circuits for shorts to ground.

4. If ok, the Body Control Module (BCM) is defective.

its alot going on if all that started happening at one time check the bcm. body control module.

Give me some more information about this problem. May be i can help.

Hi Guest,
I had this problem as well, and found the fix is actually quite easy. My issue was with the door sensor on the drivers door, but it could be any of the door sensors I imagine. The way I checked was by rolling down all the windows and closing all the doors and locking with the remote, engaging the alarm. Next, open each door individually through the rolled down window; if the alarm sounds then the door sensor is working.
To fix:
First you need to turn off your vehicle. Next, below and to the left of the steering column is a small storage compartment. Open this up and press the sides together, the door should come out. Remove the storage compartment door and reach inside to the left, where you will find the sensor that tells your car if the door is open or closed. Remove the sensor and inside you'll find three pins which have either accumulated grease and grime or have shifted out of position. Clean them off or reposition them so that you have a solid connection and press in the button to check that your lights go off (should take 20 seconds). If the light goes out (make sure you have your dome light positioned to "door") then your problem should be fixed.
Hoped this helps you and others!

press the lock button on the remote then press the remote start button. if this does not work check remote start status using steering wheel buttons

Your ignition switch needs to be replaced and then your PassLock needs to be re-learned. Very common problem on the Ions.
