As far as I know you need a special tool (Tech II) from Chevrolet to program the remotes. Don't think you can do it on your own. You can double check your owner's manual but unfortunately I think you have to go to the dealer.
Hi Kim, When you ordered the new key the dealer should have asked for the chassis number? That gives them the codes to pre program. so that it should activate and deactivate the alarm, if that is the problem! ? Regards John
Walk out to the vehicle with a new battery in the key fob and press the lock AND unlock button at the same time while you stand close to the vehicle for 7 seconds. You will hear the doors go thru a lock and unlock cycle, your fob is now programmed. This will sync existing programmed controllers, security sync. to program new remotes:In the trunk, connected to the wireless remote controller (driver side on wheel well, need to remove 'mat') is an empty connector with 2 wires connected. short the two connector pins. The locks will all cycle. Press and hold lock/unlock buttons on remote until locks cycle on/off. repeat for other remotes. Remove short across connector pins. Test new remote(s).Warning:existing remotes are deprogrammed, only remotes programmed will work from now on.This worked on my 1998 Cavalier. Be sure battries in new remote(s) are good! Answer Locate the data link connector under the dash (under the steering column). Ground out pin #8 of the DLC (top right port) with a jumper wire to any piece of metal close by (I use the e brake hardware). The door locks will then lock & unlock to let you know you are in the programming mode. Simultaneously press & hold the lock & unlock button on one of the keyless entries until the locks cycle (this lets you know the transmitter has been programmed). Repeat this step for your second transmitter. You must reprogram the 2nd transmitter within 60 seconds of programming the 1st one or you have to start over. Note
You are going to need to recalibrate the remote to the vehicle. As long as the remote works correctly which i think it should. It will actually tell you how in the owners manual. I am not current with the HHR as i have not worked on one yet. They must be reliable!
if it is a ford remote or ford factory alarm remote cycle the key from off to run(usually 8 times) untill you hear door locks activate. at this exact time key needs to be in the on position.touch unlock or lock on all remotes being programmed and make sure door locks respond to remotes. then turn key off ending programming mode.then try your fobs they should work
It took me a few attempts to program a new keyless remote for my 2002 Chevy Blazer. Insert key into ignition but don' turn it yet. While holding down the UNLOCK switch on the door, the trick is to cycle the ignition ON OFF ON OFF as quickly as possible then release the UNLOCK switch. If done correctly the door locks will cycle 1x to acknowledge. Then hold both the unlock and lock buttons down on the remote for about 15 seconds. The locks should cycle again to confirm...Hope this helps.
