Keyless Entry problem

I replaced my stock head unit with a double DIN (2000 C5 FRC). I have since learned that you need to have the stock unit for the keyless entry to work. Has anyone figured out a work-around?

Thanks in advance.

Don't know where you read that. The OEM radio has nothing to do with the keyless entry. Now, if your installer hacked into the BCM wiring, that could be a problem.

Definitely bad Intel there. I have an aftermarket HU myself and had no issues with keyless entry

Agree.......no impact from the OEM.

I agree that no longer having the stock HU should not cause an issue. Have you tried retraining your fob? Perhaps you need a new battery.

Thanks everyone! I didn't think the information was correct as I could not find any evidence of anyone having that problem. Looks like a FOB issue because it will not "learn" from the car. I'll try a new battery as soon as I can find one and give it another go.
