How do you program a new keyless enrty remote for a 2004 chevy cavalier ls sport

Hello Cathy

It does indeed have keyless entry. It needs reprogramming when you get a new remote. Also if you disconnect the battery. Usually a local car alarm fitting shop, or an auto-electrician will do it. Plus of course a Ford dealership.

If you have some "new" key, could try to re-programed and synchonized, you must have all remote entry transmitters (maximum of four) available before beginning this procedure. To reprogram the remote entry transmitters (accordign with the Lincoln LS Owners Manual) :
1. Ensure the vehicle is electronically unlocked.
2. Put the key in the ignition.
3. Turn the key from the 1 (LOCK) position to 4 (RUN).
4. Cycle eight times rapidly (within 10 seconds) between the 1 (LOCK) position and 4 (RUN). Note: The eighth turn must end in the 4 (RUN) position.
5. The doors will lock, then unlock, to confirm that the programming mode has been activated.
6. Within 20 seconds press any button on the remote entry transmitter.

Note: If more than 20 seconds have passed you will need to start the procedure over again.

Hope this helps (remember to rating this answer and leave a testimonial comment).

my 2006 impala keyless remote dont work i change the battery still the same problem the spare remote same problem how to solve this problem

Close all the vehicle doors.
Insert the ignition key into the ignition lock cylinder.
Press and hold the DOOR unlock switch.
While holding the DOOR lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
Release the DOOR unlock switch. The doors will lock and unlock to confirm the program mode.
Press and hold the LOCK button and the UNLOCK button simultaneously on one keyless remote. After a delay of approximately 15 seconds , the doors will lock and unlock to confirm the programming of that transmitter.
Repeat the previous step to program up to four transmitters.
Turn the ignition switch to the RUN (one more click forward) position in order to exit the keyless entry transmitter mode.
Operate the transmitter functions in order to verify correct system operation

you have to contact the dealer.then give them the VIN number they are the only ones that have it

You should have it scaned to see if you have any codes. It has a RCDLR (remote control door lock reciever) this is the module that recieves the signal from the fobs. If it has a problem then the system will not work. If it has to be replaced then a dealer will have to program it for you. Good Luck
