Where is the remote receiver on a 1998 Camry

[Peter wallis]

I have a camry 2000 SXV20R. The controller receiver appeared to have gone dead. The key transmitter was still working. The 25A door fuse all good.After getting quotes of upwards of $2000 to get it fixed.I doubled checked. The dome light and boot light were not working. I checked the doom light fuse and it had blown (7.5A under the bonnet). I replaced it with a 10A spare to see if it was connected to any of affected circuitry.And sure enough it most certainly is. Everything is back to normal. I will be buying a new 7.5A fuse to celebrate.And also thanks to Cosmichobo who gave me the idea.

Hi legends,

I recently bought Camry 1999, and I'm trying to repair everything I can. Car came with one fob (famous unbreakable thingy, with button cover gone and flat battery of course).

I have managed it to open and I choose the way to put the battery out of the pins - done, without breaking it. I bought CR2032 and put it into a place. Nothing, nothing happens while programming mode activated. Battery is in contact and button seems to be working fine (you can hear clicking).

 

Then I simply gave up and tried to looking for new Integration Relay... one day I met bloke explaining him what am I after and he told me he has 1 fob at home but its from Corolla. OK let's give it a try. I set car into programming mode and after the procedure 3x on/off, etc...  I got flashers slowly blinking but only 2 times. I started to getting happy 🙂 but at the end Corolla fob does not work at all, but at least I got some response from car...

Any ideas? I want to avoid buying a new fob for 100$...

 

Cheers!

Hi,

I don't know if Toyota does this, but other makes have little RFID chip in the fob, separate to the electronics, which somehow validates the fob. Using a fob from a different car, even if the same model, may not work, because of this.

Hi Herb, thanks for reply. I reckon this shouldn't be the case. Upper image is a original fob for Camry and if battery gone dead the only option is to go to dealer and buy a new fob for 100$. And you can also pair multiple (up to 4 fobs) to a car. 

The fob from Corolla (lower image) you can open and change batteries easily. As I mentioned in previous comment,  it was recongised by the car (in a strange way) but finally does not work.

 

It looks like to me that Integration Relay is OK since it recognsied the Corolla fob and the issue will be the original fob. Probably the button is gone or I don't know what else in the circuit board. Will try to measure it today if it is sending the signal.

Hi Martin,

What exactly does or doesn't your remote do? If you can unlock and get into the car, but it doesn't start, that could be that RFID chip. 

We had that happen once, after I replaced the worn out case, with the silicon buttons with a new case. I didn't realise about that chip.

Hi Herb,

 

it's very simple fob, just for central locking and unlocking. It has nothing to do with immobilizer or starting the car. 

See below actual photos how it looks like. Now the old battery is out and it does not work with new CR2032 either. There is no visible damage to the circuit board or battery pins. Hard to find out somebody with same fob around Bunbury/Perth, I would like to try it out...
