Programming remote to open doors

dealer only

Unfortunately you are not able to program a 2012 Hyundai Elantra key fob remote without professional equipment. I would recommend calling a few local automotive locksmiths in your area as they are usually a bit more affordable than the dealer. There are many vehicles that you can self program a key fob to and Key Fob Programming Instructions can be found here:

You need to get an aftermarket coded key which can be cut by the serial number of the vehicle.
You need to be a locksmith to get the cut codes or know a locksmith.
Then you have to get the car to the dealer and have the key programmed using the Tech 2 scanner.

You can take the car to the dealer and have them give you a key, programmed and everything but it will cost around $300 for the 1st key.

I bought a 2001 Catera for $1,500.00 because it had no keys.

I used serial number to get key codes and cut the key; doors opened and seller retrieved her personal stuff.
I towed car to dealership and had the key programmed; $130 for 10 minutes work (min 1 hour shop charge).
I then programmed 3 more keys (using a key code reader) instead of letting the dealership rape me.

BTW, they (dealer) also want $350 for a programmed door remote; the stock remote!
Instead, I bought a remote starter unit (Bulldog) with 2 remote fobs for $100 and now my wife can start and find her car easily.

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!

you need a scan tool to do the job. either take it to the Lexus dealership or call up your local locksmiths, a lot of them can program remotes for less than the dealer.

A Locksmith can cut and program keys. You likely did not save anything buying the blank online, locksmiths already have them on hand, and the key itself is not the major part of the fee.

I can not find a model EL, must be strictly Canadian

You may find a locksmith that has been background checked on a link from our website. I am not putting the link here, as it likely is a TOS thing

Don't buy it from the dealer, just buy a used remote from eBay. Use these instructions to program it.

1. Confirm that all doors are closed and the ignition key is out of the ignition cylinder.
2. Open the driver's door.
3. Within 10 seconds, Insert key into ignition turn to ON position and back to OFF and remove the key.
4. Within 20 seconds, close and open the drivers door 3 times. (Drivers door should be open)
5. Within 10 seconds, insert key into ignition turn to ON position and back to OFF and remove the key.
6. Press and hold both the LOCK and UNLOCK buttons together on the same remote for at least 5 seconds, the doors will lock and unlock (that's a very good sign)
7. Within 5 seconds, press the LOCK button on the same remote and release. You just programmed your remote ??
