cant reprogram remote! locks have no stamina!!

[Tucson4runner]

so i lookup up the directions to reprogram a new key fob but when i went to do it my runner wouldnt let me. directions say to have ignition off and to cycle the locks 5 times then to close the driver door and repeat. well when i try and cycle the locks the first couple times it works perfectly but once i hit 4 or 5 the locks seem to die out and only half lock or unlock. anyone else had this problem? if i wait a few seconds the locks work perfectly again. and they sound really strong so i dont think they are losing power. ive never had problems with them until now and it only happens under continuous use. is there any other way to program a remote? also ive got a transponder key i need to program. not sure if there is a thread but if someone finds it before me please post it. thanks in advance

Your lock actuators are worn. My driver's door one does this on occasion. Especially when it is hot outside. I was able to program my new key fob by manually 'helping' the driver's lock as I performed the sequence. It will only work if the locks fully cycle so you will have to manually help each lock. If it is more than 1 lock that is worn, I think your only solution is to have someone sit in each seat by the worn actuators and manually help each one cycle. Or, get new actuators.

I had the same problem on mine. Just had to do it manually. Took a few tries but finally got it to work. Actuators are just tired.

i think i read you can overheat them and burn them out. careful...

Also depending on the condition of your battery it might help if you perform the sync with your engine running so you are running off alternator power vs battery power. helped with me anyways. as for programming the transponder key, i think you might have to go to the dealer for that. at least for the engine immobilizer part.

have you checked here:

so all locks have to cycle? i cant just do the drivers? lame. well i think the drivers is the only one that is getting "tired" but this will be my last attempt. dont want to overheat them. thanks everyone got answers to both my questions in 15 minutes! :trophy:

I thought car had to be off?

 

[criera]

my bad, i guess i misremembered. i did have to fire it up between attempts though to recharge the battery, it was on its way out.

I think all of my actuators are pretty much toast. I was able to program my new fob while only manually aiding the front drivers door lock. That website someone linked above talks about the timing of your lock switching. Its not as much of a race as I thought before I read that.

Pretty much every 3rd gen I've ever been in does this.

They're just old and do that if you keep cycling them. Once you give them a second, they work just fine. The procedure requires you lock and unlock 10 or 20 times, that's enough to make anyone's locks flip out.

Same thing happens when the 4Runner sits in the heat.

Guess I'll price the lock actuators from Toyota and decide from there.

 

[Tucson4runner]

well i can vouch that with some help it works manually as well. i had to have someone do one of the back doors while i did the drivers door but it worked and i now finally have a spare key fob. now if only i can get pointed in the direction of a key programming thread....

CoB - let us know what you find about the actuators. I'd like to replace mine, but I'm not sure how much work it'll be.

Edit- wow! $102 each! And, if I replace these (maybe just the driver side), will I need to reprogram anything? I wouldn't think so...

Just do them one at a time.

BTW does you car turn over lightning quick? Because it might not be the locks at all, it could be the battery. I have gone through many batteries on my 4Runner and never had any lock problems.

How to establish it is not the lock actuator:
* With the car running at 1500+ RPM use the lock/unlock feature; is it still tired?
* Take a voltmeter and measure the batteries voltage (with car off), then post it here

12.8 volts with runner off. Normal right?
