99 Grand Am GT keyless entry problems

I have a 99 Grand Am GT. I started to have to push my lock button on my remote 2 or 3 times before my horn would blow to activate my keyless entry.
(I think I'm saying it right) But anyway...all of a sudden it wouldn't work anymore. My light doesn't even blink in the inside of the car. I replaced the battery in my remote, but still nothing. Any suggestions?
Any suggestions are appreciated.

If you have replaced the battery and still no power, there is a shortage somewhere. Take it to the dealership and see if they can fix it or get you a replacement.

Yeah that or it could've come unprogrammed, In a Grand Am GT, You can program the remote to lock so many seconds delayed, or turn the horn chirp on or off, it tells you everything to do so in the owners manual. I would check that, because the whole thing could have become unprogrammed.

I have since reprogrammed my keyless entry remote to my 99 Grand Am GT. I would like to thank everyone who replyed to my message.
