Another Keyless Entry Question Thread...

Just bought and drove this '04 AC from Texas back to CT, didn't come with fobs and trying to add them.



The RS3200 programming procedure works so I must have that system, but I bought

$35 For 98-05 Toyota Scion Keyless Entry Remote Key Fob 2btn BAB237131-056, 08191-00922 - 2 PACK

these remotes that have been linked on here a lot with FCC ID BAB237131-056, no response from the truck. I did clear all the fobs already and replaced the battery in one of the ones I bought, still nothing.

Am I missing something? I was thinking maybe buy an OEM fob which according to this thread is p/n 08191-00922 but I feel like this should've worked? Is there a way to check what FCC ID I need to be sure or are all RS3200s BAB237131-056 and I got bad fobs?

 

There's two types of RS3200 remotes and you have to make sure you get the right one or it won't program. Easiest way to do this is buy one of each and send back the one that doesn't work.
The two remotes are identical except one has a red led on top and the other doesn't

 

Weird that makes a difference, do we have individual part numbers for either? These were the no-LED fobs so I guess I need the LED one

 

I ran down the part number at one point.

Did you read the community megathread yet, "keys" section? You know you need to issue the command to ERASE all previously existing remotes if it won't take the new ones, right?

My guess is, the memory is full, and it won't take another key because you haven't cleared the old fobs out yet. Not an uncommon issue.

 

The only P/N I've seen is

$35 08191-00922 - 2 PACK

08191-00922 and both LED and non-LED versions come up when you search it hahah. Might just have to order it and see what happens.

I did already remove all keys, it locked/unlocked 5 times like it should. And yup read that megathread before I picked er up

 

This is all I can tell you: https://www.tundras.com/threads/key-fob-replacement-2002-tundra.55779/page-9#post-3353208

That's tied to my '06 AC which also has the RS3200 system.

But seriously, I got used OEM ones from fleaBay and one (or two?) from a local junkyard on the cheap, they keep them behind the counter over here. Worked great. I don't trust anything new, unopened from scAmazon or fleaBay, you'd be a fool to do so.

 

Fair enough, the dealer is cheaper then ebay funnily enough so I just ordered one there. Zero indication if it's the LED version or not but I'm thinking it is

 

In that case, here's the other thing I can tell you about fobs.

Ignore the links on those, it links out to scAmazon. Bottom line is, the dealer will be able to tell you right I think.

 

All I know is that the one WITH the LED worked for me, and the one WITHOUT the LED did not.

 

This is another good thread with internals and fob troubleshooting instructions: https://www.tundras.com/threads/keyless-entry-issues-solved.148105/

Here's a picture of both styles, with the FCC ID on rear, I should probably edit that thread I just linked with this pic.

With LED (ending -056) worked for me, and I was able to program the middle one (starting G043) to mine as well. And the last one, ending in "BBX", we have confirmation from another 2005 AC owner it supposedly worked for his truck, and also a 2006 DC owner, and another DC owner, and even another DC owner, but the part number traces back to a RAV4 I think? And it comes in some interesting variations like so.

08191-00922 was the ticket, it's the one with the LED. Works great

 

Curious, what's the FCC ID on the rear?

 

$35 BAB237131-056 , 08191-00922 - 2 PACK

BAB237131-056

 

Wild. So the OEM part with that FCC ID worked, but scAmazon-purchased aftermarket ones wouldn't?

 

Yup. Same FCC ID on both, Amazon one didn't have the LED is all

 

Bizarre. Technicall with same FCCID, should be the same internals. I did notice while tearing down mine, the one w/o LED on the plastic shell actually did have LED on the circuit board. But ... yeah, time to return to scAmazon

 

Oh interesting, maybe the LED doesn't matter it's just a terrible part. Yep those were returned the second they didn't work lol
