405 Key fob not working!! help

Just my luck to have something else go wrong with my L reg petrol saloon, the
key fob has just packed up on me, problem is the alarm has an imobilser, so I
can not get the car started without disarming the alarm.
Its not the batteries as replaced them last month and the red light on the
key fob is working? and ideas please? its a single button key fob. valeo, can
i buy a replacement if so where from?

 

I had an L reg 405 and the key fob (plip) was Infra Red and appeared to be
the same as my wife's present 306 except for having only one button. The
key can lose its programming and, for the 306, can be reprogrammed as below,
hopefully the same might work for the 405 omitting the second button in step
3.

1. Turn the Ignition switch to the accessory position using the key without
the remote plip attached.
2. Hold the Plip key close to the central locking receiver mounted in the
roof console.

3. Press the large plip button and then the small plip button on the remote.

4. Repeat for second Plip key if required.

5. Turn the ignition OFF.

6. After 5 seconds the Plip should now operate.

I originally got this info from
http://www.peugeotdiesel.com/Program_Keys.html . Hope this helps.

 

Just came across this for the Xantia which came from the same stable:

1. Ensure all doors are unlocked using the key.

2. Press and hold plip key button until LED stops flashing.

3. After releasing button, LED will light constantly.

4. Press the Plip Button once, and LED will extinguish.

5. Open the door and hold the Plip key near the Ignition switch, and
press the plip button one time.

6. Now turn the ignition ON, and wait 10 seconds then turn ignition
OFF.

7. After 5 seconds, Plip should now operate.

 

My key is built into the fob so it would be impossible for me to carry out
these actions? is it maybe cause my car is petrol different key fob?

 

incase this does not work any ideas where i would buy a new one?

 

the key fob seems to work intermittently does this still mean that it needs
re-programing?

On my wife's 306 and my old 405 there were two keys, one with the fob (plip)
and one just a plain key. I take it you only have the one. You can
obviously buy new keys from Pug dealers but I believe they often come up on
eBay both new and used. You may be able to get a key cut more cheaply from
a non Pug stockist.

I cannot guarantee that any of the fixes I posted will work but they are
worth trying. Other than that, someone else on the group may have more
accurate info.

 

Unfortunately, on the 405, the key cannot be programmed at all. And
you can't use just any key. You need to buy one from a dealer and you
need the code either from inside the key or inside the receiver in the
roof. It is printed on a small piece of paper. You may also need the
make (I think either Valeo or Neiman). With this the dealer can order
one from France and it may take up to three weeks to come. If your key
is the type that cannot be seperated from the plip then the new key
will come like that and will need to be cut.

 

My experience with 405 keys is similar, the led on the key works okay
but the key only intermittently operates the lock/immobiliser.

I fixed mine by taking it apart and resoldering the IR led and driver
chip onto the PCB. During the life of the key, there is enough flex in
the assembly to cause a dry joint which makes the key plip operate
intermittently.

I've done the keys for two cars like this, same fault both time. Find
an electronics engineer near you who can cope with SMD components and
you'll be surprised how quick it is to fix!

Good luck

Thanks Nigel, that will at least save him trying unsuccessfully to reprogram
the key. I was hoping my suggestions would help but I had a nasty
suspicion that the 405 would be different.

my friend has had a look at the fob for me to see if he can solder it, so we
will ahve to wait and see but thanks for lettting me know that i can not re-
program the fob, i'm a she by the way keith not a he.but thanks for trying to
help it is appreciated

 

Does your 405 have a button on the side of the steering column to disable
the alarm? If so you might be able to get round it. But again you really
need two keys. Might be worth getting a plain copy made of the key by any
locksmith, hardware store or motor supply place which also cuts keys.
This you can then use in the lock to open the door.OK this will make the
alarm sound I know.
You then switch on the ignition switch whilst depressing the alarm button.
This will cancel the alarm and allow you to start the engine. This must be
done within 10 seconds of opening the door.
This came from the Haynes manual for a '93 306, but I am sure it also worked
for my '93 405. (Now gone to the big scrapyard in the sky).
Hope it works for you.

 

Apologies for changing your gender. I assume that Lee is a forename and,
if so, I should be ashamed of myself, because my daughter's second name is
Lee (my wife liked the actress Lee Remick). Post back and let us know
how you get on.

The sterring column button only disables the ultrasonic alarm inside the
car. The only way to turn off the alarm is the keyswitch under the bonnet.

lol no problem Keith on the gender change, its times like this i wish i was a
man and the Lee is short version of my name which is to distinctive to use as
a sign on name as its not a common name at all.

the chap who said about pressing the button on side of steering column, it
won't work when my alarm goes off it sets off the imobliser so the engine
would not start. so i'm gonna try to get it resoldered and see if that helps
failing that will have to do what you guys said and order a new one.

 

Does your 405 have a button on the side of the steering column to
disable

Certainly on the 306, that button, if pressed when turning ON the ignition,
will disable the immobiliser part of the alarm too.
It has to be done in the correct way. I do not have the key for the switch
under the bonnet on the 306, and so whenever I have to disconnect the
battery, I have to go through the above process before I can start the
engine, as the alarm resets when the battery is connected again. The key fob
drains its batteries so quickly (known fault on these) that it isn't worth
putting new batteries in just for this.
However, it seems it doesn't work on the 405 in question.

 

Sorry to hear of your problems here. I have a 405 saloon L reg, and
think its the business. My fob button recently stopped working (button
wore out), and so I took it apart, disarmed the car by shorting the
pin terminals under the button, and just use the key without the alarm
(I also got another successfully cut by a standard key smith). If you
open and shut the doors just using the key, the alarm is not activated
but central locking works..I will fix a new button to the fob
eventually and reuse the alarm.

Richard my friend looked at the PCB board and he said that the joints look
fine, but one of the metal bits near a hole look worn down to almost the
green board underneath, so looks like i may have to fork out for new fob,,
doh!!
