Its tricky not a simple task it usually requires a bi directiinal scan tool (a really good one ) never the less here a few things that might help the first step in the procces is to find out what happened somtimes it happens when simply changing the cars batery it can be bricked/locked
other times it can be more complicated do you know when it first began ? was there any work performed right before this happened? did you have any issues with the key fobs or anything out of the ordinary? Did you try to reset it ? Is there a light on the dash ? These are some of the questions to get you started let us know but also consider that if you dont have a pretty capable scan tool that can can retrieve a code to open the gateway and comunicate with the modual and execute the proper procedure to unlock it or re program it ..you may need to bring it to the dealer or a shop that has the tools and the knowlage to help this is at least a good start
Good luck hope this helps

There are 2 basic ways you can try without a scantool but theyre the most basic ways to re synchronize the imobiler (somtimes) and dont alway work if it has compleatly lost contact with the key fob ot might need the more involve way with a scan tool but it depends on whether or not it had other ongoing problems so before
you can try them a few needs have to be met .like"
Does the car still run ? If no "
Was the car starting normally every time before this happened ?
Is the Batery fully charged ?
Is the Key fob and batery in good condition ?
Does the fob still unlock the car ? If not "
Do you have the original fob that came with the car ?
Anÿ problems with any of the doors not locking somtimes before this ?
Did the alarm sound off once in a while randomly seemingly without cuase?
Any warning lights on the dash since this started ?
Have you tried to reset it yet using any of the standard basic methods? If yes than you might need a scan tool
There are 2 basic ways to try without a scan tool but it depends on how and why it got locked in the fist place if you can provide us with as many details as possible as to what you think the problem is we might be able to help let us know ..
Good luck
