Hello, What has happened is your remote has lost its programming.. Just like with most electronics, when something is reset or powered off, or even when the battery dies ....the programming software is lost. The remote has to be reprogramed either by a dealer (suggested) or by an aftermarket outsource..Hope this helps...This could help with almost all remotes.

How to break into 2003 gmc envoy,without hurting it? Key won't work,remote won't work,battery is dead.

You can usually go to the passenger door and use your key to unlock it, then reach through and open drivers door. After that pull the hood release and change your battery. If it still won't open with a key on passenger door then you will have to call a locksmith who will bring a special tool to open.

Would a dead battery stop your key from turning on in a 2003 gmc envoy

Sounds like a flat battery. Just enough to power your lights but not enough to power the starter motor. Try recharging the battery.and check battery connections are good.

Car alarm goes off when I use the key to open doors or start engine on my 2006 GMC Envoy. Problem started when I installed new battery.

Not familiar with the envoy, but most all GMC trucks have a alarm reset button under the dash by the steering column to reset after battery problems. Why did you change the battery? It may also be your starter has shorted out which will set off the alarm. Good Luck

Check the battery cable connections for corrosion. Clean and tighten if necessary. Get the battery checked out at a dependable auto shop. Some places will check them for free.

I changed the battery on our 2003 envoy, and now it does not run smooth

You will either need to reeducate the computer or have the dealer do it for you.
If you call them they can explain the procedure.
I believe it is start the car cold, let it run till warm.
Put your foot on the brake, put it in "D" then "R" then back to park, after that it could take as long as a month for the car to finnish learning.
But I would call the local Chevy dealer to get the low down for your vehical.

Envoy A/C problem connected to Recent Battery Change...

Yes there is a connection with A/C going wacky and the battery disconnected for any reason, due to poor design. Upon re-connection of the battery, our actuators have a good chance of blowing. Pretty common problem, they should have disconnected Fuses #10 and #28 before hooking the battery back up.
