Sounds as though the motor may have quit working, check your fuse or the relay in the underhood power center. The key still works correct? Do you hear any noise when you try the remote switches? If you do the rods may have come loose or the holders may have broken.
Reprogram the keyless entry remotes. Take the vehicle to a Hyundai Service Center.. they'll give you an estimate of repairs (parts, labor, tax, time-frame, etc.). This way you'll know EXACTLY what's needed and the fix.
Firstly, open your glove box and make sure Valet Mode is not enabled, if it is not, follow these steps.
Step 1: Open drivers door and leave open. Step 2: Lock and unlock the driver’s door using the power door lock switch on the door. Step 3: Insert key into the ignition. Step
4: Turn key to on position and return to off position. (IMPORTANT - use
ON position NOT ACC position). Do this 3 times within 10 seconds. Leave
key in the ignition. Step 5: Open and close the driver’s door 3 times. (Door should be left open after this step). Step 6: ECU should respond by locking and unlocking the doors. Step 7: Press any button on remote #1 twice. ECU responds by locking and unlocking the car doors. Step 8: Press any button on remote #2 (etc.) twice. Each time the ECU will respond by locking & unlocking the doors. Step
9: Remove the key from the ignition and the ECU will respond a final
time with a series of door locks and unlocks. You're done!
It is possible that the receiving unit on the vehicle is not operating properly. Whether that means a broken wire, bad circuitry in the receiver, or other problems it could the case, BUT more often than not, the key/remote was exposed to some kind of magnetic or high power field, effectively remdering the unit useless. Strong magnets, electromagnetic fields or even staying to long on a department store demagnetizer could lead to these problems. Go to the dealer and be prepared to take the hit, a replacement coded key can run several hundred dollars, but unless you swapped the battery and happened to get a bad new battery, than the dealer is the only solution, I hope this brief explaination shed a little light for you in the future.
Hello, It seems as is if you have a remote that will not lock the doors all the time. There can be a couple of reasons that it wont work at times.1 it may have a weak battery,2 there may be some kind of residue inside the key fob itself such as tea,coke,water, or even sweat. This will short the fob out at times.Thank you
