Trying to get my remote fob/plip locking working!

[mjb]

There's 2 plastic hinges at the bottom of the glovebox with plastic pins in. Slide the pins out (towards the centre iirc) and be careful not to lose them.

I take it from there the Central Locking ECU will be easy to remove? Also it will be the same ECU/Central Locking system if it's and same type of fob and it's the same immobiliser keypad type system?

Well on mine removing the glovebox doesn't let you see much more. You're still on your back half lying through the door. The thing is... there's a lot of electronic boxes under there and personally, I haven't got a clue what's what!

But I'd think only one will go click when you operate the central locking (two person job then)

[sidmon1]

Just to confirm also before I get these replacement central lcoking ECU and fobs that they should fit mine and the fob part of the key can be interchanged with any other key.

[mjb]

Let us know if you manage to separate the blade and fob - and how. It's something I've not sussed yet

[sidmon1]

Fingers crossed this will work!

Hi first of all the 96 406 does not have a transponder- secondly the rest procedure you described doesnt seem right, i reset mine recently buy inserting the key in the ignition, turning to ignition position one, hold remote button down for ten sconds then remove key wait ten seconds then try locking...mine worked fine!

If it doesn't have a transponder, why don't the doors lock when you press the button with the key in the ignition?

Open up your key and you'll see a little black rectangular block inside. That's the transponder.

That syncs the key plip to the central locking; it has no effect on the immobiliser which the transponder chip is coded to.

As the owner of a business that has cut and programed them for the last ten years, the basic job of the transponder is to prevent the engine from been starting unless a correctly coded key is used-also if you can remember way before the use of transponders, remote central locking was been used..... As i first quoted "the 96- 406 does not have a transponder" and hence the reason why early 406's where fitted with imobilizer key pads.

You didn't answer my question...

Also a later model 406 without keypad immobilises and demobilises itself in exactly the same way as a Jan '97 model with a keypad set to 'auto' mode. If you open up the steering column cover you will see the aerial around the ignition barrel and If you open up the key you will see the passive RF transponder.

when the keypad is in auto keypad mode the imobilzing and demobilizing is operated by the activation and deactivation of the remote locking.(anti-start system)
If the system allowed you to operate the remote locking while the key is in ignition position one you would in effect be trying to imobilise/alarm the car while the ignition is on....(the remote locking will operate with the key just sitting in the ignition but not turned)
This sytem is not a transmiter-responder system,(transponder) they operate at a dirfferent frequency to central locking.
If the locking remote fails in auto keypad mode then the doorl ocks have to be opened with the key and the four digit code enterd in to the keypad as in manual mode.
when the keypad is in manual mode entering the four digit code is what demobilizes the engine-not the key.
When new Peugeot supplied d8s with Secondary keys or (valet key) these are flat and completely made from metal no plastic fobs or plastic tops just metal (So no where to hide a transponder) they unlock the doors and start the engine but wont lock/unlock the glovebox.
The black oblong plastic block in the inside front of the key does i agree look like a transmiter, so today at work i inserted my key into our reader/writer, it displayed the message "no transponder detected" i have a 97 exec turbo.
It may well be that some later d8s and d9s are infact fitted with a transponder system, but my original post which was queeried by MJB was that "1996-406s did not have transponders".

If you exceed the 30 second period between the doors unlocking and the car re-immobilising, you can put the key into the barrel without turning it, and press the button. Pressing the button DOESN'T lock the doors but deactivates the immobiliser. Usually you don't do this though - you hit the starter, hear the immobiliser beep, and turn the ignition+aux off, press the button and try again.

Like I asked ONCE AGAIN, if it doesn't have a transponder, why don't the doors lock when you press the button with the key in (or near) the ignition barrel?


By the way, what's that thing that fits around the barrel on the servicebox "anti-theft device alarm"? The one called "AERIAL" part number 616060... before you start saying it's the receiver for the plip electronics, look up part 6552ZJ (the central locking transceiver) on "Central door locking". Note the key is part 9170L3 on both diagrams...

As you originaly used your car as an example to dispute my first post which related to an early 406 (1996). I therefore had assumed you to have an early 406. ....You must have a later model with a transponder, poss with the plip that must be pressed before the engine will start.

In 1997 there is a change over period when 406s started to use fixed code transponders, my car is an early 1997 and does not have a transponder.
Any 406 manufactured upto 97 do not have a transponder.
406s Manufactured during 97-99 have PHILLIPS fixed code transponders.
406s Manufactured 99 on have TEXAS crypto transponders.

So to have asssumed that all 406s have transponders was incorrect...
As my original post stated "1996 406s do not have transponders" is actually correct!

As a comparison...My car does allow the central-locking to be activated by pressing the plip with the key near or in the ignition barrel before 30 seconds providing its not past ign1-because it doesn't have a transponder.
