Unlock a 1998 RAV4 after remote stopped working?

Question

Hi. I just locked my wife's 1998 RAV4 with the keyfob remote, only to return moments later and the remote no longer functions. We've been having trouble with both of the remotes and right now, *NEITHER* of them will open the car.

We've gone through several batteries and I am coming to the realization that these remotes are a problem. Anyway, If we unlock the doors, the alarm goes off. I can't call Toyota because it's Sunday. Other than disconnecting the battery, anyone have any ideas for disabling the alarm with only the ignition key?

Thanks in advance.

Depending if you have the older system or the updated one, either you turn the key to the on position, or you turn the key in the door twice to unlock. To reprogram the key fob, here's the way to do it
First, some background info. You will need to find the ECU for the alarm/keyless RS3000 system. Mine is under the drivers seat. Looking at the side with the connectors on it, there is a small button or hole on the right-hand side. you will need to press the button or insert a paper clip into the hole to press the switch inside, following the instructions below.

The Status Monitor is the the Red LED light on the
dash that says "security" under it. This procedure seems quite simple, although the manual still advises one to contact a dealer to do it. It sure isn't worth $76!
Be sure that you follow the procedure exactly or there is a chance that you might mess up the programming of the
original remote. If that happens, just follow the procedure again to add the remote back to the system.

1. Insert key into the ignition switch and turn to "ON".

2. Press and hold the ECU's programming switch for 3 seconds. The Status Monitor LED turns on for 5 seconds.

YOU MUST PERFORM THE NEXT STEP WITHIN 5 SECONDS!

3. Press and release the remote control's top or bottom button (whichever one you want to operate the system).
The Status Monitor LED turns off.
The Piezo "chirper" chirps once.
The exterior lights flash once.

4. Turn off the ignition. The ECU will now operate with the remote just programmed.
