Can a yamaha rav 230 remote be programmed back to factory settings?

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.

Great news, your 1998 Toyota Camry Key Fob is self programmable. Below are the programming instructions. Be patient, it might take you a few times to get this right. It is all about timing.

Most remotes can be self-programmed. If this procedure does not work, you must have your remote programmed by a professional automotive locksmith or dealership.


Obtain all remote transmitters for this vehicle.
1. Insert key into ignition and turn ignition switch to ON position.

2. Locate the ECU (Engine Control Unit) and press and hold the ECU PROGRAMMING button for 3 seconds. The ECU will be located under one of the front two seats, the trunk, or under the dashboard on the drivers side. You will need a small pointy object like a pen to depress the ECU button. After pressing the ECU button for three seconds, you will see the STATUS MONITOR LED turn on for 5 seconds. Vehicle is now in programming mode.

3. Press and release the top button on the remote. The STATUS MONITOR LED will turn off. A chirp will be heard as well as one flash of the exterior lights.

4. Turn off the ignition. Programming is now complete, test remotes for proper programming.

a engine sensor of wwhich there are a few get the OBD read should give you a code for the problem part

Try this:

KEYLESS ENTRY PROGRAMMING

Have all remotes for the vehicle on hand.

Make sure all the doors and rear hatch/trunk are closed during programming.

Only need to use 1 remote to get into program mode but all remotes must be programmed during the same session.

Each step must be completed within 5 seconds.

1. Sit in the car with all doors/trunk tightly closed

2. Turn the key to the ON position, marked by "II" on the ignition bezel so the dash lights come on, then within 5 seconds press the "Lock" button on the remote for 1 second or so and release the button.

3. Turn the key to the OFF position, marked by "I" on the ignition bezel - dash lights go off.

4. Repeat steps 2 & 3 three more times (A total of 4 times) - each step must be done within 5 seconds of the previous step.

5. Upon the 4th turning of the key to "ON", press the lock button on one remote, the locks will make a cycling sound (clunk), locks will NOT lock or unlock at this point, they will just make a noise. The system is now in programming mode. Do not turn key off.

6. Within 5 seconds of entering programming mode and within 5 seconds of each other, press the lock button ON EACH remote you are programming, for a second or so and release. This step needs to be completed within 10 seconds. Each time a remote button is pushed, the locks should cycle. Up to 3 remotes can be programmed.7. Turn ignition completely off and remove the key. Step out of car and close door. The remotes should be programmed and should work. If you have a trunk/hatch release, the button for this feature needs to be held for a few seconds before the trunk/hatch will "pop".

Try this please!
'98 - '02 Isuzu Rodeo and Trooper and Honda Passport(with factory keyless entry) Instructions for programming. 1. Get in car and make sure all doors are unlocked. 2. Open driver's door and leave open. 3. Put key in ignition. 4. Turn key to 'on position' (dash lights on, but do not start) and back to 'off position' 3 times in 5 seconds or less. (you must turn the key very fast) 5. Close and open driver's door 2 times in 5 seconds or less. 6. Turn key to 'on position' and back to 'off position' 5 times in 5 seconds or less. (turn key very fast) 7. Close and open driver's door the doors should lock and unlock twice after this happens push the lock or unlock button on the remote, doors will lock and unlock. Push the lock or unlock button a second time and doors will lock and unlock again. You are finished! The above sequence erases all previous codes and adds the new code as #1. If you are adding a second remote, you should follow the same sequence with the exception of step 6; instead of turning the key to the 'on position' and back to the 'off position' 5 times in 5 seconds or less, do it 3 times in 5 seconds or less and then continue to step 7. ***Remember to turn the key to the on and off position very fast. This works! Follow directions EXACTLY. I had to try 3-4 times before getting it to work. I failed to go exactly by the instructions the first few times.

Here are the instructions from the factory service manual:
1. Enter 5-digit permanent entry code into the keyless entry keypad.
2. Within 5 seconds of pressing last button of code, press the 1/2 button. All doors will lock then
unlock confirming you are in programming mode.
3. Press any button on first Keyless Remote within 5 seconds of pressing the 1/2 button. Locks will
cycle to indicate succesful programming.
4. If you are programming more than one Keyless Remote (Including any exsiting remotes) Press
any button on second keyless remote within 5 seconds of previous remote. Locks will cycle again
to indicate succesfull programming. (If the keypad light goes out before all remotes are
programmed the entire process must be repeated).
5. Press the 7/8 and the 9/0 buttons simultaneously on the keypad to exit program mode.

To figure out if you have factory keyless entry,place the key in the ignition and turn it foreward 5 times in 10 seconds. This means forward just till the dash lights come on, but do not start it. If the doors lock and then unlock, you've entered programming mode and you have a factory system. You'll need to get on line and purchase a factory remote, (I didn't see any on Ebay) and following this guude:

- Cycle ignition from OFF to RUN 5 times within 10 seconds, ending in RUN. (this may take 8 times)
- All doors will lock then unlock to confirm programming mode.
- Press any button on 1st transmitter.
- Door locks will cycle to confirm programming.
- Press any button on 2nd transmitter (up to 4 transmitters total possible).
- Turn ignition to OFF.
- Locks will again cycle to indicate end of programming mode.

Hope this helps.

The procedure goes like this. First get in the car and lock all the doors. Secondly insert and remove the key repeatedly until the turn signal indicators on the dash flash twice simultaneously, it should be like seven or eight times. Then turn the key on and press the lock button on the remote and the lights should flash again. After that turn the key off and manually unlock and open the drivers door, then shut it. Wait a few seconds then try the remote. 

Mine has done this and i as well do not have a working remote. To disengage it just put the key in the driver door lock and turn for 2-3 seconds and it will disengage. i didn't even know mine had an alarm until coming out of work one night and it went off and i could not get it to turn off unless i went to "unlock" the door and hold it there for a few seconds.

How long does it take before it goes dead again? A few seconds? Days? Is the battery old?
