Hi, I bought a Xantia Activa a couple of months ago. It was registered in November 1998 but built in 1997. When I first went to see the car at a fleet car centre in Leeds, it couldn't be started because they didn't have a code for the immobiliser.
They then sent the ECU off somewhere for decoding or reprogramming and called me when it was ready. The car doesn't need a number entering in order to start the engine and "keypad code" 0000 is written on the service history document in pencil.
The red and green lights on the keypad are both on dimly all the time, go bright when you switch the ignition on.
A few things I would like to know are:
If I have a flat battery or have to disconnect the battery for some reason, am I likely to end up with a car which won't start.
If I take the keypad out of its holder there is a label on the side with serial numbers etc on it. There is also the number 2169 stamped on the label, could this be the original code?
I would also like to know basically how you use the immobiliser, can you change codes or is it fixed for each car, are you locked out after a certain number of wrong attempts etc? Unfortunately, when I bought the car it didn't have the owners manual with it
Many thanks
Richard

it will not be the original code because from the factory they all come with the same code 1111 or 0001 with regards to the 2 lights on dim this is not right either when ignition torned off after awhile the red light should flash. something wrong there somewhere (dont think it is an activa thing they are a rare breed).
Sorry, the red light does flash when you leave the car, the green light remains on dimly.
The number stamped on the label on the side of the keypad unit could be the i.d. of the quality control guy in the factory I guess.
Reading through these forums I gather that the 0000 code is a service code.

richard,
here is the infomation on changing the code etc (as copyed from owners manual):-
WARNING: AFTER 3 SUCCESSIVE FALSE ATTEMPTS; THE KEYBOARD WILL BE LOCKED AUTOMATICALLY FOR ONE MINUTE.
FIRST PROGRAMMING OF THE CODE, INGNITION ON,
1- enetr the code 0001
2- press key C
3- entre your personal 4 figure code
4- press the C key to validate
four flashes of the green waring lamp and an audible"beep" indicate that the information is recorded.
TO CHANEG THE CODE, IGNITION SIWTCHED ON,
1- enetr your old code already in the memory
2- press key C
3- enter your new confidential 4 figure code
4- press key C to validate
four flashes of the grenn waring lamp and four audible "beeps" indicate that the information is recorded.
SECURITY PROCEDURE
the two codes (old & new) ar valid until one is used to start the engine.
should there be no confirmation (4 flashes & 4 beeps) turn off the ignition, then tun on and start the whole prcess again.
if more than 4 figures have been entered by mistake, before pressing key C, only the first 4 will be memorised.
if both red & green warning lamps are flshing simultaneously, this indicates an incorrect entry or a malfunction.
turn the ignition off, thenturn on and start the whole process agin. if this condition persists, consult the nearest citroen dealer. (yeah right<img src=icon_smile_big.gif border=0 align=middle>).
NEUTRAL MODE
this mode is the only one that prevents automatic locking of the system on switiching off the ignition.
1st possibilly- enter your personal code already memorised then press the key D/N (DEFER/NEUTRAL) for 2 seconds.
2nd possibilly- follow the code changing procedure using 0000 as the new code.
to get out of this mode, enter your confidential code with the ignition on.
DEFFERRED LOCKING MODE
press the D/N (ignition on) to delay locking of the injection system for one hour.
durring this time, you need not re-enter the code tio start the engine. the deferred locking is indicated by flashing of the green warning lamp and an audible "beep" for 30 seconds after the ignition being turned off.
to cancel the deferrewd lopcking press key D/N.
idenification of system status from out side the vehicle.
LOCKING ENGAGED
the red warning lamp lights up continupusly for 10 seconds after the system has been activated then flashes until the ignition is nexted turned on.
LOCKING DEFERRED
the red warning lamp starts flashing after one hour and continues until the ignition is next turned on.
IN CASE OF BREAKDOWN OR BATTERY DICONNECTION, THE CONFIDENTIAL CODE REMAINS IN THE MEMORY.
hope this is of some help for you rich

Thanks for that info, the problem is that I don't have a personal code. The immobiliser seems then to be in neutral mode and I assume that if the battery is disconnected it is likely to revert back to whatever is the "default" mode, which probably means that it will need a code that I don't have. It may be that "0000" is the code that's programmed in and if a one minute lockout is the only consequence of experimenting, as opposed to the risk of permanently locking the ignition, then I might have a go at entering codes.
I don't have a D/N key though, I have the keys 0 to 9, C and S.

I've got a Xantia with the keypad same as you describe. With the ignition switched ON, the keypad will be in one of three states. 1 - The red lamp will be lit signifying that the security device is engaged and the engine will not start. You will need to input your personal code. 2 - The green warning lamp will be lit, signifying that the security device has been disengaged, and you have sucessfully entered your personal code. 3 - The red and green lamps are both lit, signifying that there is a fault within the system. I have the Citroen book of the coded anti-theft device dated March 1996 which covers the keypad you describe. You can have it in normal mode requiring your personal code. You can have it in service mode, to allow garage to start the vehicle without knowing your personal code. The book does not describe any way to disable the immobiliser. It describes what to do if the keypad is locked. I can supply more info if you email me at lozian@tiscali.co.uk.

the D/N code pads were droped after a couple of years there is no way to defer the later pads by keypad the fact you have a dim green light could possible mean you could have a bad earth somewhere on system, but the fact you dont have to punch a code in after locking car means the system has been bypassed.
My primary concern is, whether there is a possibility that this thing could re-set itself after battery disconnection, leaving me with an immobilised car and no code.
I've found a few places on the web which advertise keypad immobiliser decodes so I might ring round for a quote. I would have to send the ECU and keypad off though so would have to wait till I don't need the car for a few days.

I got brave/reckless this morning and disconnected the injection ECU and keypad. The car started ok after reconnection and will in fact start with the keypad disconnected, so I guess that something has been done to disable the immobiliser. I'm not that bothered so long as I am not likely to be stranded somewhere and I now feel that is unlikely.
I was wrong that the red and green leds were on dimly, it was just ambient light being reflected back. The red and green lights both come on when the ignition is turned on, Lozians' post tells me that signifies a fault. The immobiliser may, like the ABS go into a fail-safe mode when a fault occurs.
I could take it back to where I got it from but I doubt I would get much joy. I wouldn't buy a car from there again as there were one or two items which were supposed to be done for the MOT and weren't.
