Peugeot 406 Key Fob

I’m looking to see if a keyfob is available for my Peugeot 406 2.0 LX
1996/P.

I’ve been told by my very unhelpful Peugeot dealer that they can only
supply the fob if I can unclip my courtesy light and read off a number
on a sticker on the sensor.

I’ve looked (and in the process snapped off the lugs on the courtesy
light panel - Doh!), but all that’s there is the wiring loom for the
two lights and the base of the aerial. Does this mean I’ve not got it
installed on this car, or am I looking in the wrong place. They also
told me it’s infrared - surely that can’t be the case? My experience
of this is that it’s of very limited range and unreliable for outdoor
use.

If it’s not installed, how difficult would it be to fit a receiver
that I would raid from a scrapyard? Can one be fitted from a dead Pug
or is it a major job (ie reprogramming the ECU or changing it!). I’ve
got no problem with removing panels or lining if that’s what’s
involved.

So why is this unhelpful? If you want a key to work your car then it does
have to be matched to the code embedded in the rooflining receiver.

IR is the reliable one. Radio units are the potentially un-reliable and
readily jammable ones. IR has opened my pug reliably for 10 years

You would still need the matching key for the scrapper

I didn’t mean that he’s unhelpful in this matter. They’re generally
unhelpful. Seems to be a lot of bother for them to help me on almost
any aspect, and wants to be the one to do everything for my Pug. It’s
this unhelpful attitude that is stopping me from buying a car from
this particular dealer in future.

Is the receiver actually in the courtesy light area? Or am I looking
in the wrong place?

Are the buttons generally on the key, or available on a separate fob?
I’ve got an aftermarket key, not the original one. I understand from
the dealer that all I’d need for them to get an IR sender was the
frequency code on the receiver. They’d be able to order up a key with
any frequency apparently. However the dealer refused to tell me
whether the unit was on the key or on a separate fob.

My dealer has also told me that if I need a new key, it will cost
£150. Is this right, as they insist they’ve got to change all the
locks. On previous cars (of many makes), other dealers have been able
to work on the chassis or engine number to get the correct key.

I mention that I’ve found IR to be unreliable because I’ve found in
the past (particularly with 3rd party alarms) that I’ve needed to be
very near the car to activate it, and it’s been a battery drain. If it
works, fair enough but I’ve had problems with it in the past.

 

IR receiver is in the front middle under the antenna.
If there is no receiver there must be a loose connector at that place.
Key can be made from chassisnr.
Also I have a scheme for making your own transmitter.
The code for this transmitter can be determined from the receiver.

I have a '95 405. The receiver is in the headlining- look for a black
plastic cover. This is IR transparent but blocks strong sunlight etc

My key has a single button, a red led and an IR led

There is no concept of a 'frequency' with IR keys. The dealer is talking
bollocks. The signal to open your car rather than another one is in the code
that is modulated onto the IR signal

This may be true. The new key has to transmit the right code as well as
being the correct mechanical profile. Maybe they can specify the profile or
can't be arsed to find out?

Nigel, another contributor to this group is a Pug master tech and may well
be able to answer this point.

Yes IR is short range- about 4 cars lengths but in 10 years, I've just put
my second set of batteries in - 2 at 99p each so not much of a battery
drain.

Just had a look, there’s no receiver. However, at the front of the
headlining, behind the black lining on the windscreen in the centre,
there’s a hole, about 5mm in diameter. Nothing is behind this though.

Was this only available on certain models or as an option? I’m
thinking it’s probably not installed on my car. However it seems odd,
I’ve got aircon on this model, and you’d think with that installed
remote locking would have been standard! Either that or the previous
owner had problems and ripped it out.

I don't know anything about 406s.It was just as your 406 is virtually the
same age as my 405 I'd assumed they would have similar schemes.

Hopefully someone in this NG with an early model 406 will be able to help.

sensor should be under the glove box at the nearside footwell area
look for a small black box with a visible metal plate on the outside
(aerial)
easier way is just to get the dealer to look (ask for the resident master
tech though,sounds like last time you got an idiot instead)

 

Hi

Some of the early L & LX spec 406s did use the awful infra red remote
locking keys & the sensor will be in the roof consoul.

The GLX, SRI & Executives always used the RF remote keys & the sensor for
this is buried behind the glovebox.

Also the U.K. spec 1996, 1997 & some 1998 406 GLX, SRI & Executives ( IE:
The cars with 4 electric windows from the factory ) had a total closure
feature from the remote key.

Open all the windows, Deadlock the car with the remote, Big button first &
then within 3 seconds the little button, Stand back & watch those windows
close on there own, This was never mentioned in the handbook.
On the high spec cars, The handbook might be in its little storage tray
under the front passenger seat ( L & LX dont have the tray )

This feature was removed in 1998.

SOME but not all of the early L & LX spec 406s did use the awful infra red
remote locking keys & the sensor will be in the roof consoul.
But then again they also used the RF key like the high spec models.

Thanks for all the advice guys, looks like I’m going to spend tomorrow
afternoon led upside down in the passenger compartment. As well as
this, I’ve got the problem with the speedo transducer, and the air
recirculation flap motor (to be disconnected!). I understand they are
all in this area.

Does the RF receiver have a frequency code on it that I’d need to
quote to the dealer?
