Remote central locking 02 corolla

batman1

Hi,

The remote central locking has stopped working a few months ago. It wont reprogramme using the fob so looks like the main unit is knackered. Main dealer wants 150 to replace. I have a feeling it was an added extra as the fob is not part of the key and does not have a toyota mark on it. It's an extra square piece on the key ring.

Can anyone tell me where the unit might be located so perhaps I could get it out and get a replacement elsewhere.
rather than paying through the nose for it at the main dealer.

Thanks

If it is an aftermarket remote set-up it could have been put any where, behind the dash....in the drivers door, etc.
You would probably be better off buying a new system on ebay. At least then you will know the fobs will work with the control unit .

I fitted this to the wife's yaris in about 1/2 an hour.

That looks like a good deal for that product.

Although, not being the most mechanically minded, I was hoping to plug out the old unit and plug in a new one.

As regards wiring one up, I wouldnt know where to start.

Toyota dealers generally use meta remote locking kits on corollas

ive not sure, but i think corolla central lock works on vacuum pipes. i think youll need extra door lock solenoids ... like that- that

Vacuum pipes? It's not a rolls!

he he, but all jap cars , what i had, and wanted repair, or instal central lock, i had buy those solenoids. even my mazda 626 '89, skyline' 96. so no need to be rolls to have vacuum pipes for central lock.

Just to clarify,

The central locking still works using the key in the driver door.
The unit is still in the car etc but just stopped working.

Is there much work involved in wiring in a new unit?

On a phone, but they look like electromechanical solenoids not pneumatic!

Wiring in a new unit is fairly easy. The harder part is stripping the door to access the wires.
Have a search of some of the toyota forums for more info regarding wire colours and removing door cards.
The most important tool you will need is one of these;

These (or similar) are available in all motor factors as well as Halfords and Maplins.....and Ebay. You will need it to find which wires to connect the Lock and Unlock Trigger wires to.

Is it one of these?



Or these?




Both are meta

"for testing broken wires" does it pick up on voltage just by running it along the outside of the insulation (like a Fluke Volt Alert for mains) or do you have to poke it thru?

mgbgt1978

If you're asking about the tester i pointed out, this has a sharp point to poke through the insulation and touch the copper itself.
For this particular job you are using it as an "earth wire" as nearly all modern central locking systems use a negative pulse for both locking and unlocking. In other words when a particular wire is earthed the doors will lock and another wire will unlock them when earthed.
The reason for using this type of tester is simply to ensure that if you hit a live (+) wire it won't blow a fuse....just light up the bulb.

What's the advantage over a multimeter? (interested from my own point of view, not questioning the suggestion!)

First of all the control box will be behind the glovebox ( open the glove box and pull hard on the box and it will pop off) second, there is a connector there with all the wires needed to wire up another kit, ie you do not need to take a door panel off on a toyota to find central locking wires!!!
