Doors won't unlock with fob

I've got an '03 Tundra Access Cab. Recently I started having this problem where the doors will lock with the fob, but will not unlock with the fob. I thought maybe this is a common problem and somebody knows how to diagnose and fix it. And maybe some tricks and tips. I've done a little research, but I want to hopefully be confident what the problem is before I start pulling doors apart.

 

I had that happen before and I had to use it 2 ft away for it to work. A new battery fixed that issue.

 

Yep, new battery. If that doesn't work......new fob.

 

I found (probably by a post on this board) that if I hold the fob against my cheek that the door will open when it otherwise won't.

 

I replaced the battery right away and tried the spare fob. Same results. That’s what made me think the problem is in the door.
How do you get a new fob?

 

Not sure if this would apply to this particular year of vehicle, but sometimes when programming a fob there is a sequence of things you have to follow to get the fob paired to that particular vehicle. Maybe see if there is a sequence with your vehicle and try it with your current fobs.

 

Before getting any further, can you please post a picture of your fob so we know which system we're advising you on? RS3000, RS3200, afermarket?

 

This is what they look like

 

If the dealer doesn’t carry it, eBay or a new compatible aftermarket fob would be the next logical choice. See this thread for help:

Looks like you're using the RS3200 TVIP security on the truck. Programming instructions are here for Reg Cab, Acc Cab, and some Db Cab.

I'd buy a different remote and see if that gets you sorted; if not, you've now got a spare remote. Bill just gave the link, you basically need the key fob with FCC ID "BAB237131-056". Searching for the phrase BAB237131-056 anywhere on the internet will net you a replacement. The hardest part is programming it - it normally takes me 2-3 tries before I get the order/timing of steps correct, and I've done it half a dozen times on this truck already. Doesn't seem to get any easier with repitition, so keep trying the exact instructions in the linked document.

 

Thank you. I’ll report back
