is a bit interesting. Does anyone know about the "keypad immobiliser" it aparently has? I though keypad immobilisers were only fitted to much much later PSA cars (like about 1995 on)
Is there an easy way past these?

CX with a keypad immobiliser?
This is not a signature.
I agree about the immobiliser. my 89 16 valve has an alarm fitted by Citroen UK I believe for insurance purposes but it doesn't immobilise. Our 94 Zx has one but it looks like an after-market one but our neighbour's N reg TD Estate has the keypad (and a dash shelf mat!)
To be honest I don't think keypad immobilisers were not invented in 89. My father's 93 Range Rover which has a factory fitted secuity system doesn't have a keypad (and that was hideously expensive when some sucker wasted his money on it when new)
From some research I did into malfunctions of the security system of the Range Rover a modern 'thatcham 2' in fact only controls 2 circuits so the chances of it being very difficult to bypass are remote.
Wonder who bothered to fit it? I'd have thought that while of interest to an enthusiast, it could have been left safely with the keys in it throughout its life - bit like our ZX I suppose.

Re: CX with a keypad immobiliser?
A CX wouldn't have had a Citroen factory fitted keypad immobiliser, they weren't used until about 1993 or 94 if I remember rightly.
My dad bought a new ZX TD some time in 1992 and paid for a factory fitted immobiliser, the type Citroen were using at that stage was a microchip on the keyring which had to be plugged into a socket on the dash before the engine would start.
There are quite a few aftermarket keypad systems available though, eg
http://www.astrogen.com/sc2001.htm
so the one on this CX could be almost anything.

Some Late series Petrol Turbo 2 Cars did have an an onboard computer, trip, mpg etc etc.
They look a lot like the later style immobiliser, I cant actually remember if they ever did immobilise the car, I have a sneaky suspicion they may have done but not really sure, im getting older and the memory is not what it was.
Im sort of thinking you could turn it off and on as required.

Hi Guys,
Serie II Turbo I's had the onboard computer (mine has that), possibly very few GTi Turbo II's had the onboard computer as well.
As far as I know, most CX2500 GTi Turbo II Series II cars did infact have a factory keypad immobiliser. It is NOT aftermarket.
My Xantia has the kepad immobiliser and I personally think they are a pain in the arse. I think most in the CX's get dissabled by entering the code then unplugging the keypad.
seeya,
Shane L.

If you haven't got the right parts for this you're buying a pretty but deteriorating garden ornament!
The trip computer appeared soley on the S2 turbo 1's and ONLY the GTi Turbo 2 cars use an immobiliser lock-out. It's code is embeded in the combined fuel AND ignition ECU - a bit like the chip on your swanky new switch/credit card and can only be changed to another one IF you know the first code...
OR have a handy ECU WITH A KNOWN CODE for this EXACT model!!
You could try the old 1111 as per Xantias etc as it may have been set to the workshop setting. With the Cx wiring being totally flaky as is it's wont, these do get circumvented "naturally" along the way by invisible magical forces that cannot be explained apart from the mere mutterings of "well, it is an old Citroen..." and some do work without any code. [In this case I'd take a rank oufield guess and say in a past life a previous owner has switched the immobiliser to an inactive setting]
As I said from the start, this CX on ebay will only work IF you get an unlocked/able ECU as the guy does mention it used a code in the past.
I've heard of these PCB gurus that promise to unlock things for all sorts of monies BUT HAVE NEVER met a person who's actually used said gurus to see if they get anything to work - you may get cable if you pay enough and you're lucky tho...
Happy bidding.

Of course you could simply buy it, park it in the shed and try every code from 0000 to 9999 ..... You are sure to find the right code ... Eventually

The vendor has confirmed that it is indeed a factory fit immobiliser. Aparently it is similar to what was used in the mark 1 XM.
The main question is; which unit "knows" what the code is? If it's the keypad, then there must be a way of "pretending" to the ECU's that the code is correct. Otherwise, if it's the ECU that "knows" what the code is, Can the ECU be interrogated to find the code, or even re-programmed to disable it....
Otherwise, it is indeed, a slowly decaying ornament.
Is there a time-delay between entering codes? If not, then this is actually a viable option. If there's a 2-hour delay after entering the code wrong 3 times, then it could take a while (the best part of a year in that case!)DoubleChevron wrote:Of course you could simply buy it, park it in the shed and try every code from 0000 to 9999 .....

It's NOT the keypad - you can chop and change these with no difference to the code - as I said, it's in the ECU. IIRC, there is a time limit after the 3 attempts to input the code although I'll check my handbook this evening.
I think if you put out an APB request for a S2 T2 ECU WITH a code rockin'orse poo will be easier to find...
Mind there was this:
ebay item number: 4585981327
though I wouldn't expect them to know the code. A Cit specialist/indy is your only salvation and they know what they've got so will charge accordingly!!
I could have had a remapped one a few years ago that'd would have largely 'Maiconicsed' my T2 but I couldn't/wouldn't swap an ECU with a code...

Im horribly tempted to bid on it and then go and sit there entering the numbers till you hopefully get lucky.
It would be worth it just to see the guys face when you did actually manage to start it and drive away

I seem to remember that AlanS had some real fun with an (aftermarket) alarm/immo fitted to one of his BX'es ?
The CX would have a similar immo system. These will go dead with a dead battery - and will need some time to recharge an internal NiCd cell for the memory.
I would be surprised if a NiCd cell from that age is still functional at all after such long a dead time. They usually collapse rather fast after a discharge when aged - and then they mostly shortcircuit themselves. This will for sure leave any immo circuit dead as a consequence.
This is BTW the most common "mysterious" death of many earlier ECU's or microprocessor circuits in general.
Recent NiMh cells are much more longterm reliable.

Rightho, found the handbook stash...
The '87 and '88 edition contents are the same and state:
"Ignition security lock
[according to equipment]
1 2 3 C [RED LIGHT]
4 5 6 M
7 8 9 0 [VERTICAL SWITCH "AUTO" AT TOP]
This security device locks the electronic ignition system when a confidential 4 figure code has been programmed. The vehicle is delivered new with a 0-0-0-0 code. To make use of the security device this code has first to be changed.
Ignition switched on.
• Red warning lamp off = engine can be started.
• Red warning lamp on = ignition security device engaged.
To allow the engine to be started, the 4 figure code must be entered and the red warning lamp must be off.
In case of error, press keys C or M and re-enter the code. Each time a key is pressed, the red warning lamp flashes to indicate that the information is recorded.
To change the code.
Ignition switched on - Red warning lamp off.
1 - Press 'M' key, the warning lamp flashes three times.
2 - Enter your new confidential code [0-0-0-0 if still the original code], the warning lamp flashes three times.
[In case of error, press 'C' key, and re-enter the complete new code. 'M' key allows the cancellation of the modification in progress].
The two codes are then valid until one is used to start the engine.
The code used will then be the only one valid.
Activating the device
Switch in "AUTO" position
Switch ignition off.
Locking the doors will automatically lock the ignition.
Switch in "NON-AUTO" position.
Switch the ignition off.
Locking the door will not lock the ignition.
To lock the ignition, first switch it on again and press key "C".
Deactivating the device
- Switch ignition on. Warning lamp on, Engine cannot be started.
- Key in the confidential code. Warning lamp blinks as each key is pressed.
- If the code is correct the warning lamp goes out.
- Start the engine.
WARNING; In case the confidential code is forgotten, it is necessary to replace the ignition control unit.
In case of failure or battery disconnection, the confidential code remains in the memory. With the engine running, pressing the keys will not affect the ignition system. If the engine stalls, it can be restarted by the ignition key."
Right that's it!!
Nothing stating lock out after inputting 1000's of attempts, so, IF you really want the car...
Myself, I think I may bid, borrow an ECU off mine and drive it home to mothball...
Have fun...
