Remote keyless entry?

I got my '99 Mustang base coupe (V6) from a used-car dealer. Remote keyless entry is listed as a standard option for my car, but the dealer didn't give me the remote that should have come with the car. Apparently the seller didn't give them one. Is there a place where I can order a new remote that can be configured to work with the existing system, or will I have to buy a whole new keyless entry system?

Yeah. If you have the STEALTH anti theft system like I do, you should be able to pick up a remote from the dealer. If it's an aftermarket symstem, then go to any car audio/alarm shop and they should be able to program it for you!

if its standard option, then it is factory, you can get one MUCH cheaper on ebay for your car.....to program it I think all you have to do is put it on your keychain, turn the key (ignition) on and off like 5 times, untill the doors lock. It should work then
