Question about 2001 Hyundai Elantra
Where is the keyless entry reciever located. Trying to reprogram new remotes and cannot locate it. Thought we found it, but cannot find the set/off button. Hyundai Elantra 2001
The ETACS unit, which controls the alarm, is bolted to the dash chassis
and is located immediately behind the climate control cluster. You need
to gain access to this unit to code a new remote. Technically, you are
not coding the remote; what you are doing is re-programming the ETACS
module to remember and accept the secret code transmitted by the
remote. The ETACS unit is designed to remember and accept up to two
remote codes. If you wish to add a third remote, the dealer must
program the third remote to utilize the same code from one of the other
two remotes (called code-saving). There is no way to do this yourself.
1) Remove the dash facia using the "Easy Dashboard Removal" DYI posted
here by member kmr327.
2) Remove the four screws securing the climate control cluster, pull it forward, and remove the wiring harness.
3) Using a flashlight, (and cramming your head), find the sticker that marks the location of the set switch on the ETACS unit. It is on the right side of the ETACS unit, below the antenna input (the antenna can be unplugged -- it utilizes the same type connecter as the AM/FM antenna). Note the positions on the sticker for "Off" and "Set". By default, the switch is in the "Off" position, which is the normal functioning position. Next to the sticker is a small piece of tape covering the recessed slider switch, which you can not actually see. Remove the tape with a razor blade or by picking at it with your fingernail.
4) Once the tape is removed, use a jeweler's screwdriver or other similar small tool to flip the switch into the "Set" position. (Note: if you unplugged the antenna from the ETACS unit, the antenna must be plugged into the ETACS unit at this point and the car's battery must be connected). You are now ready to code the remote. NOTE: When you code the new remote, you must re-code your old one at the same time or the old one will no longer work. To code the remote, press either the lock OR the unlock button of the remote once. Do the same thing for the second remote. Try to do the second remote within two seconds of the first one. Slide the switch back to the "Off" position. Verify that both remotes function. If they do not, set the switch to the "Set" position again and repeat the procedure. If you continually run into problems, try coding only one remote. I have heard on some of the forums that the second remote has to be pressed within a second of the first and that it may take several attempts to be successful. I did not encounter this problem.
5) Reassemble the dash facia.
Hope this information is useful!
