Send me a PM with your VIN and I will look it up.

Well, that should not happen - changing the car battery should not affect the keys.

Do the keys have good batteries?

If all is okay then somehow the central locking and alarm module got confused and may need to be re-programmed.

thanks...keys have good batteries...they both flash green while pressing any button on them but dont do anything other than start the car...rear hatch cant open either

I know, I have a different car from possibly a different era, but . . . Sometimes when the car won't respond to the buttons on the key - even after starting the car - it takes using the key in the door lock to make it better. This has only happened a couple times since owning the car for four years. I was fearful of needing to get the system reprogrammed, but nope, just needed to manually lock and unlock the car. go figure

Thanks..will keep trying that...now the PSM light is on without it being turned off on the dash..tricky gremlin stuff going on here!

Have you checked the main and aux car batteries for proper voltage? An under-volt battery can cause weird things to happen. On my car it triggered Limp Mode which only allowed the trans to shift up to third gear.

Thank you,yes have the new battery on a tender charge and always above 12v.No rear battery...appreciate any and all responses...PCM doesnt work either..fuses all good..

* now car feels like emergency brake is on but it isnt and wont move in drive or reverse...Help!

Don't know if this will help, worth a shot.The key remote might of lost it's memory due to the battery changes.

 

If the vehicle is not started or unlocked with the remote control within 7 days, the remote control standby function is switched off (to save the vehicle battery).

1. In this case, unlock the driver's door with the key at the door lock. 
   Leave the door closed in order to prevent the alarm system from being triggered.
2. Press button 1 on the remote control.

The remote control is now activated again.

Any idea how a DIYer can reprogram  the central locking and alarm module ?

Maybe Durametric... if not then it will take a PIWIS tester. A few shops have PIWIS.
