I recently replaced my car battery after it died, and ever since then, my keyless entry hasnt worked... any quick fixes for this without taking it to the dealer?

 

nope just one... i just bought the car about 3 months back.

 

i'll check that but i doubt thats it... i think the ECU needs reset to the proper frequency for the remote.

 

================================
Maybe you should look in your owners manual. There is a section on fob training.

 

[QUOTE=seabright;1576510496]I agree about resetting, but you will need a replacement transmitter from a dealer (costly) to be matched to match your vette. When the dealer matches the new FOB to your vette, your FOB must also be matched.
==============================
This information is not correct!

 

asnytime the car battery is dis-connected, the FOB needs to be re-programmed. Check your owners manual.

 

I can't speak for vette's specific but I was in the car business for many years and had plenty of dead gm batteries and NEVER had to re program a remote.

 

changed my battery....both fobs OK.
If it was the battery change, BOTH of your FOB's would have stopped working, not just one. Change the battery in the FOB first

 

Two processes for FOB - Do NOT need the Dealer!

Both out of owners manual

To match transmitters to your vehicle:
1. Turn the ignition key to ON.
2. Clear any warning messages on the Driver
Information Center (DIC) by pressing the
RESET button.
3. Press the OPTIONS button on the DIC several times
until the blank page is displayed, then press and hold
the RESET button for two seconds.
4. When the message FOB TRAINING is displayed,
push the RESET button once. The message
HOLD LK + UNLK 1ST FOB in the DIC
will be displayed.
5. Press and hold the LOCK and UNLOCK buttons on
the transmitter simultaneously for 15 seconds.
6. When a transmitter is learned (matched), the DIC
will display FOB LEARNED and then prompt you
to learn the next transmitter.
7. Repeat Steps 5 and 6 for each additional transmitter.
8. Remove the key from the ignition.
The programming mode will shut off if:

You don’t program any transmitters for two minutes.

You take the key out of the ignition.

You have programmed three transmitters.

Resynchronizing Your Transmitter
Your RKE system uses a continually changing code
for increased security. Normally, the receiver in your
vehicle will keep track of this changing code.
If your vehicle does not respond to your transmitter,
do the following to determine what’s wrong:
1. Get closer to the vehicle and try pressing a button
again. Your battery may be low. (If so, see “Battery
Replacement” in the Index.)
2. While standing close to your vehicle, press the
LOCK and UNLOCK buttons on your transmitter at
the same time and hold for seven seconds. This will
attempt to resynchronize the security code in your
RKE transmitter.
3. When resynchronization is achieved, the horn
will chirp.
