95 pontiac keyless entry broke

PLEASE HELP MY KEYLESS ENTRY STOPPED WORKING AND I CANT FIGURE OUT HOW TO FIX IT.  MY REMOTES HAVE NEW BATTERIES AND WHEN I START MY CAR THE DOORS LOCK LIKE IT WAS WORKING.  BUT WHEN I TRY TO USE THE REMOTE TO LOCK OR UNLOCK IT DOESNT WORK.  WHAT ARE THE ODDS THAT BOTH REMOTES GO BAD AT THE SANE TIME?  SLIME AND NONE I THINK.  I CANT FIND THE MAIN BOX TO SEE WHERE THE KEYLESS IS COMING FROM.  CAN ANYONE HELP ME PLEASE???  THANKS KYM  kym

first turn off the dam caps. is this a factory or after market keyless.

does any other buttons work, like panic or trunk pop.

Nothing on the remote works at all.  i have 2 remotes and nothing is working.  Thanks Kymkym

Its made by DEI they produce valet products. Did you have a dead battery in your car lately? Are the leds/green lights illuminating on the remotes? Some cars Have factory ignition controlled locks, I am not sure on this model.  Sounds unlikely both remotes would go bad at the same time though...You'll also want to locate the brain this is were most of your testing will be done. I'm betting its somewhere under the drivers side dash.....
