Key Rob Replacement- Ace couldn’t do it

I went to Ace Hardware to finally get a new key fob programmed. The key fob I had stopped working after it went through the wash. The tech guy said it wouldn’t allow him to reprogram it. Any solutions as to why this is happening? Hoping to avoid going to the dealer and paying the big bucks.

 

I'm kinda glad I don't have keyless entry; I can get a copy made at Home Depot for just over two dollars!

 

Make a new one - tomskey.com. Cheapest option you will find.

Here is a thread w/some discussion - https://www.tacomaworld.com/threads/finding-replacement-key.829399/page-2#post-29734617

 

He said Key FOB, not the key itself.

You can program your own Remote Key FOB.

Get a replacement FOB with the correct FCC Code. FCC ID # GQ43VT20T it should be molded in the back side of the FOB.



Use this guide to program the new FOB:

Here are the complete process for programming the remote FOBS. You may want to clear everything and reprogram the truck to receive the FOBs you have. Note: The info in RED for other models.

Try this. There are 4 modes. You should use Rewrite Mode to start over and only program the remotes you want to use.

There are four different programming commands when setting up or verifying your remote transmitter, they are:

1. Add mode, used to add a remote to your car that is not currently registered.
2. Rewrite mode, used to erase all previously registered remotes and allow you to begin again the programming process.
3. Confirmation mode, used to verify the number of remotes that are already programmed in your car.
4. Prohibit mode, to prohibit all remotes from operating the door locks.

Procedure To Program Toyota Wireless Remote Transmitters:

Begin with: The driver's door open and unlocked. Key out of the ignition.

1. Insert and remove the key from the ignition switch 2 times within 5 seconds.

NOTE: Steps 2 and 3 should be performed within 40 seconds.

2. Close and open driver's door TWICE.

3. Insert the key into the ignition and remove it.

NOTE: Steps 4 - 6 should be performed within 40 seconds.

4. Close and open the driver's door twice.

5. Insert the key into the ignition.

6. Close the door.

NOTE: Steps 5 and 6 should be reversed for the following models ONLY (close door first, then insert key into ignition):

2000 - 2005 Celica

2001 - 2003 Prius

2001 - 2005 ECHO

2001 - 2005 RAV4

2003 - 2004 Avalon

7. Turn the ignition switch from "Lock" to "On" and back to "Lock" at about 1 second intervals to select the desired mode:

1 time for ADD mode.

2 times for REWRITE mode.

3 times for CONFIRMATION mode.

5 times for PROHIBITION mode.

8. Remove the key from the ignition.

9. To confirm your mode selection, the power locks will now cycle "lock" to "unlock" a number of times corresponding to your key cycles in step 7.

NOTE: If Confirmation or Prohibition modes have been selected, opening the door will complete the procedure.

10. For Add or Rewrite modes do the following within 40 seconds of Door

Procedure Lock confirmation:

A. Press both car transmitter Lock and Unlock buttons simultaneously between 1 and 1.5 seconds and release.

B. Within 3 seconds of step A, press the transmitter Lock button for more than 1 second and release.

If the keyless entry remote transmitter has been successfully programmed, the power locks will cycle "lock" to "unlock" once at this time.

If there are problems with the remote transmitter or the procedure up to this point, the locks will cycle twice. If this occurs, verify that you have received the correct transmitter, and then repeat the above procedure.

C. If multiple remotes are to be reprogrammed, repeat steps A and B.

11. Open the driver's door to conclude programming mode.

 

You can't replace Rob!

Thanks Jimmy

 

Key fobs are like 12$ on Amazon anf you can YouTube how to program them at home

 

I guess @BlissfulBee has left the building...

 

Check w/Batteries and Bulbs.
They are my go to guys.

 

If my truck had an aftermarket key fob(with alarm) could I switch back to a Toyota one or is that gonna mess with the alarm?

Did the 2015 even come with alarms? I wonder why the previous owner put one in...

 

If you have an aftermarket alarm you will need the aftermarket FOB.

 

The Rob song and dance is the way to go!

 

My truck recently starting locking itself automatically after opening the doors. For instance, I'll open the doors w/ the fob and I'll be working inside the vehicle for not even a minute and then the doors automatically lock. Almost like the truck isn't sensing the key is in the truck. I know this is going to lock my keys inside the truck any day now lol. I'm assuming this might be a sign of a dying FOB?

 

Sounds like you either have some kind of aftermarket security that is going wonky, a failing door switch, something going on with the Body ECU, or a fob that has a wonky button.

Does this happen at random or is it about 30 seconds after you unlock the doors?

 

No aftermarket alarm on the truck. I haven't paid attention to it 100% of the time, but from memory, it's happened each time I've opened the door and they'll lock w/ the doors open after about 30 seconds and the key being physically present in the truck.
I was also thinking it could be on the receiving end. Whatever receives the signal from the fob might be going bad too. Happen to know what that is exactly? I gotta start googling.

 

That would seem more like a door switch issue, the auto relock will relock the doors 30s after they are unlocked by the remote if one isn't opened within that time.
Would be curious if it does it on all doors or just one.

 

Yes, all doors. I’ve had the driver’s rear door and front passenger open on two separate occasions and it’s happened.

 

Say we’ve lost all fobs so no easy FCC ID, is it possible to get off the box in the truck itself? Anyone know where that might be located?

 

^Wondering the exact same thing. My wifes 03 Lexus ES300 has no key fobs and would love to get one without paying hundreds of dollars at the dealer. I assume it's a similar process to tacomas if I can find the FCC ID.

 

@caribe makaira, I’d imagine you might know where the oem keyless entry modules are stashed on 2nd gen Tacomas?
