05 Tundra SR5 beeping when i unlock but not when i lock

Anyone know how to reset this? I would like my truck to beep to let me know when I lock it.

 

Welp, you don’t tell us what can type you have, so it’s really difficult to say.

Assuming you have the original keyless system and not something your dealer added or aftermarket unit…

And assuming you don’t have the double cabs that use BCM for keyless…

Instruction manual for programming the RS3200 in your truck is in this thread, along with everything else you need to know about your truck: https://www.tundras.com/threads/so-you-wanna-buy-just-bought-a-1st-gen-tundra-eh.115928/

Search the 1st page for “KEYS”. It’ll take you to programming manual and instructions.

 

Sorry, it’s a double cab, original keyless entry.

 

That manual should get you there but you need to heed the warning in that KEYS section about how double cabs have two possible programming sequences to enter programming mode, and the timing between steps is critical. They need to be evenly spaced. I never get the sequence right the first time, it always takes a few tries. You double cab guys have it rough, because you don’t know if it’s user error, or you’re following the wrong process.

 

Thanks for the advice, if i get the sequence wrong will it mess something up or will i just have to start over?

 

Also will deleting the key fob and re programming fix my issue?

 

Failure to follow the correct sequence with correct timing will only result in <you don't enter programming mode>. If you get to the end of the sequence and don't hear the expected chirp, wait 5-10 seconds, and try again.

Looking at the RS3200 manual (link), I'm actually a tad bit confused, because I'm not seeing chirp-by-button assignment.

I think it's worth a try, wiping the remotes, then re-adding yours. Would isolate if it's something specific to the remote.

But before you do that, got a picture of your remote? Just want to make sure we're 100% dealing with RS3200 here.

 

Yup, totally RS3200. Do you have another remote you could use to see if it's happening with all remotes?

I swear we had another similar case to this in the past, but there's too many keyless/fob threads to dig through. You could try deleting and re-adding if you don't have a spare remote. I'm curious what you'll find.

 

Yeah i actually do, i bought this truck a few weeks back, I’ve been doing a little work on it here and there. Of course I’ve been discovering things that needed to be addressed to my standards. Stumbled upon a spare fob in one of the back cup holders. I think it needs a new battery and the eye that holds the key ring is broken. I’ll let you know what happens when i change the battery.

 

I'm not 100% sure but zooming in it appears the FCC # is

$25 HYQ12BBX HYQ12BAN HYQ1512Y

HYQ12BBX which matches my 04 DC LTD original remote.

Some say the HYQ12BBX(Body ECU) were issued for factory installed and the BAB237131-056(RS3200) for dealer installed.
Since you have a DC, Toyota went to using a factory installed Body ECU starting with the 04 DC and carries over to the 05-06 DC. The dealer installed RS3200 remained same as 03 as far as an 04 AC or RC.

I'm unsure but I don't believe not hearing the beep when locking has anything to do with programming.
However, if you wish to try the procedure for a DC in case you get another remote, suggest following the below video. Haven't followed all the links given above, so the DC instructions are out there if you need them.



my 04 DC LTD remote....

 

Here is just some documentation for you on the wireless system.

 

I think i may have found the problem. Not sure how i missed this. The driver door doesn’t unlock/lock with fob or button. Saw this in a different topic. Wonder if it’s true with 1st gen?

Sounds like if one door actuator isn’t working the truck will not beep if i lock with the fob.

 

Yeah, if its not locking or unlocking with the button then its the actuator.

 

Ok, I’m not sure how i missed that, I’ve had the truck for a few weeks now, i wonder if it went out recently.

 

I was under the impression it was just not beeping on lock. But it's actually not locking on lock button press?

 

Yes that is what was happening but this afternoon i noticed my driver door wasn’t locking when i tried to lock it with the key fob. Then i noticed the button inside the truck wouldn’t lock it either. I did some digging and saw where that guy in the pic i shared said if an actuator is bad in one door then the truck will not beep at all when you press lock on the fob. Not sure if that’s true or not.

 

I think you’ve got your culprit. I would buy the OEM replacement if I were you. On most of our trucks, they sell the handle+actuator as an assembly, and just the actuator. If you need help finding the part#, PM me your VIN.


But before blaming the actuator, know that it’s possible to damage the door harness where it passes thru the door. We’ve seen it before. I think @Dook55 might’ve been the last victim?

 

I’ll check that out. I wonder though if that’s the case how the other doors will lock from the driver side lock/unlock button. You would think if it was damaged all the doors wouldn’t lock.

 

Depends how the door is wired. In the door harness, if there's a single power feed to the switch panel that feeds windows+locks, everything would be dead. If there's a single power feed for the lock actuator, and another for the courtesy light, and yet a third for the window motor, you'd only need to impact one of the two wires (either ground or power) for the lock actuator feed to interrupt power.

With all window motors and door actuators, you can test their function with a basic rectangular 9v battery. With door lock actuators, there should only be two wires, you hook up +/- in one direction, it should trip the actuator to lock. Reverse the polarity -/+ on those wires, it should unlock. Window motors can be a bit different, some use a 2-wire, others use a 3-wire (most common I've seen), and the 2-wire operates similarly to actuators, polarity impacts direction, 3-wire I always need to go back on notes, I always forget, I believe one wire is a constant power feed, and the other two wires are for up/down trigger.

Anyway, getting off-topic here. I was wrong, it was (I believe) actually @CC80guy who had the problem, but with windows, and here was that thread: https://www.tundras.com/threads/screwy-power-window-issue.145188/

He was able to deduce by opening the door to different positions and testing the function. You may try the same, as the door opens, the wiring passing through the rubber accordian-style grommet will move, and may complete the circuit.

Understand: The door harness is very simple. If you pop off the plastic cover ("kick panel" between the dash and door/floor, there's usually 2-3 connectors along the sheet metal there. One (or more) feeds the door over a combined harness. From that/those connectors, wires get bundled together, feed into the door through that black accordian-style harness, then get distributed out, to the speakers, the door courtesy/puddle light, the switch panel, and the mirror. Over years of opening/closing, if anything is rubbing, it can rub through. This is why I say what I said in reply #2 of that thread. I believe most of that diagnostic applies to you here, in that ...

• You could try feeding the solenoid directly with voltage to see if it fires
  • If it does fire, you have a wiring/harness/control pad issue, further diagnostics required
  • If it doesn't fire, you have a solenoid issue, replace the solenoid

I will tell you this, also: Before you open the door up. Before you dig into anything. Carefully pull up the control board on the non-working side. Unplug the connectors, and inspect for rot. Also, plug/unplug the connectors into their respective socket a couple of times, then test again. It's possible you just have a poor connection. I've seen a number of times where simply reseating a connector to "polish" up the contact points has resolved stupid stuff.

 

Just an update, changed out the Actuator on the driver side and it fixed the problem. Driver door now locks with switch and key fob. Truck also beeps when i lock the doors with the key phob.
