their is a way to do it but recheck battery first sometimes the relearn process doesnt work or the fob itself is dead also if auto /remote start will need dealer to flash fob ---- 2002 santa fe and followed programming instructions and eventually was able to program the new remote. But, I did not realize I had to program my existing remote at the same time. Since, I have retried programming both remotes many times with no success--the new one works, but the old one won't. The instructions were: 1) Locate switch under dash, behind fuse box; 2) Turn ignition switch on, but don't start engine; 3) Wait 5 seconds, set memory switch to SET position; 4) Press remote LOCK button; press second remote transmitter LOCK button; 5) Set memory switch to OFF; 6) Switch ignition OFF. 7) Confirm programming by locking and unlocking vehicle.

Incorrect. As long as it IS/WAS original factory alarm & key fob previously programmed to you Hyundai, it is the easiest to program yourself.
There are multiple different sites listing many ways to program, but the majority suggest you close all doors, insert key into ignition, turn only to the ACC on ignition switch but do not start, then hold down the unlock/open button on fob until the alarm hazard lights blink & you are done.

Try the following:

Good luck barry

should not be using fob buttons for entry or locking for emergency only .if keyless entry walk up to car with fob do not press any buttons see if door opens then walk away from car with fob about 20m then go back to car without fob and see if door locked if so all working fine .indicators will not flash if the above dont work take back to main dealer for diagnostics keys may need to be reprogrammed

Insert key into door barrel or ignition lock and turn key, whilst doing this press the unlock/lock button, the led on the dash should flash to indicate this has initialised the key to the car, then remove key and test operation of remote. If this fails then a new remote plus coding to the car by your dealership is needed

You should not have to reset the key fob after a battery replacement. The signal from the key fob stays the same and is programed to the reciever.
If the key fob needs to be reprogrammed then follow these steps.
1. Have all key fobs with you during programming.
2. Sit in the vehicle with all doors closed.
3. Lock all doors using the Lock/Unlock switch on the door.
4. Insert and withdraw the ignition key 7 to 9 times within 10 seconds (do not turn the key, just insert and withdraw).
5. The 4 way flasher indicator on the dash should flash once or twice.
6. Insert the ignition key and turn it on (key on, engine off).
7. Press any button on one remote and the 4 way flasher indicator on the dash should flash once.
8. If you have more key fobs to program use the Lock/Unlock button on the door to unlock the doors and then lock the doors.
9. Press any button on the next key fob and the 4 way flasher indicator on the dash should flash once.
10. Repeat if you have more key fobs. Only 5 can be programmed.
11. To exit, simply turn of the igniton and remove the ignition key.
12. Unlock the doors using the Lock/Unlock switch on the door and exit the vehicle.
13. Make sure the window is down when testing remotes in case you leave the keys inside.
14. Close all doors and test all remotes that were programmed.

Do not skip any steps or the process will not work.

If the 4 way flasher indicator does not work when inserting the key, you will need to start the process from the begining. If it still does not work the receiver may be your problem.

If the 4 way flasher indicator does not flash when pressing any button on the key fob then the key fob is the problem (dead battery or defective remote)
