The alarm and immobilizer needs to be reset. It is not as straightforward as normal. You may need an auto locksmith.

Try disconnecting the neg. battery terminal. Open the drivers door and leave it unlocked then reconnect the battery back up.

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

Put key in ignition and turn forward to start electrical system, but not the engine.
Turn key back one click.
Push the button on the alarm box under the steering wheel (sometimes by parking break) three times (3x)
You will hear two beeps of the horn confirming the change. You are done.

engine management should read the transponder chip in your key and deactivate the alarm the battery in the key is charged while key is in ignition if the key hasn't been used for a while maybe its flat

Leave key in the on position (but without engine running) for about 10-15minutes and the alarm should reset itself.

Try disconnecting the battery cable for a few minutes. This may clear the security code and allow the normal key to operate. The sensor in your tire may have gotten damaged when it was repaired (this is not uncommon). The solution, take it to a tire store, they can change the sensor if needed.

change the battery's in the key fob

you would need to conntact the dealer it should run you around 30.00 for a new clicker takes 3 secs to set up the new one

hi just connect the battery close the bonnet and do what you normally do to lock and set the alarm it should reset itself it normall for alarms to do these things yates210456
