How to reset fob to unlock doors on a 2013 Lexus that has no ignition

google how to program fob for 2011 chevy malibu for more info

On the Chevy key fob, press and hold the "Unlock" and "Lock" buttons at the same time until you hear the door lock and unlock again. This means you're all set. Re-insert the programmed key back into the ignition to the "On" position to finish the Chevy key fob programming process

I have read this 6 times and still not sure what the issue is? I have a 2005 ES330. To open all the doors with the key fob, you have to double press the Unlock Button. Pressing the Unlock button once, only opens the driver door.

The door lock module and further help is in the link.

1. Close all the doors and insert the key into the ignition.
2. Turn the key off then on repeatedly until the door locks cycle. End with the key turned on.
3. Press the lock or unlock button on the key fob. If the doors lock (or unlock), the key fob is programmed.
4. Turn the ignition to off

I had this with my Lexus. It was my first service, I said how silly that when you press the fob only the driver door opens, then I have to open the door, and press the inside button to let my wife in. The service guy said we can program it so it open on a single press if you wish, it is a safety thing. You know if you double press the open button all the doors unlock? Problem solved. Try it. If that doesn't work, it could be a few things so best to visit an auto electrician.

Yes, car will not start or will start and run for about 20 seconds and shut off if the anti theft system is active. The theft system will either disable the starter circuit, cut the fuel injector circuit or both. Sometimes you can lock the doors with either the key fob or electric door locks, then open manually with a key and then lock with key fob, wait 30 seconds and unlock with key fob or key. Occasionally that will reset the system, or turn on ignition 3 times for 10 seconds each without starting the car, (turn key to where dash warning lights illuminate, but not to the start position), wait 30 seconds then start the car, for the ECM to relearn the key code. If that doesn't work, most likely will have to be reset at a dealership. Good luck!

Assuming you mean door unlocks while parked? Toyota will not allow door to be locked using the remote control while key is in the ignition or if you with a wireless proximity key (now referred to as a FOB), while the wireless key is still in the car. If these are not the case, you may need to check out the sensor in the ignition or if using a FOB, the computer interface between the FOB circuit and the door lock.

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)

put the key in the drivers door lock and lock and unlock it three times. make sure all door, hood and trunk are completely closed before doing this.

7. With the door open insert your key into the ignition, turn to 'on' position (DON'T START), wait 5 seconds. Turn off and remove key.
8. Locks should cycle once (Car will lock and then unlock once by herself). If they don't cycle or they cycle more than once, do steps 1-7 over.
9. Now using the remote, push lock button, hold for one second, then release the button. The locks should cycle once. If not, start over and go slower.
