seconhand central locking remote

[les]

I see lots of these advertised as rf type and ir type i am guessing this means radio frequency and infa red if so what type is required for mk 1 sx regards les

[xantia_v6]

Mk 1 Xantia is IR and easy to reprogram, Mk 2 Xantia is RF and more difficult to reprogram.

[les]

managed to get one advertised as mk1 but dont seem to be having any luck to be honest i think its faulty led on side of the fob works as and when it feels tried programing with ignition on and repeatedly clicking at dome in the roof but no joy les

Watch it through a digital camera (not an SLR) and see if the IR LED lights up.

is that the large one at the front if so it is very faint and on constantly if button is held down could it be a faulty reciever

[xantia_v6]

It could be a faulty receiver, but they are normally very reliable.
If you have never seen the remote locking work on this car, then it is possible that someone has disconnected something to disable an errent alarm. Check the fuses and the box under the passenger seat.

If you look at the (clear) LED through a digital camera, you should see it 'blink' each time either of the buttons are pressed. How bright it appears to be will depend more on the 'camera' and ambient light conditions than on the remote.

If the LED is on constantly when either button is held down, the remote is faulty.

It's perhaps worth pointing out that the receiver dome has to be able to 'see' the remote LED. So IR remotes don't work when you're standing in front of the car; also wet side widows lit by the sun can mean that the signal from the remote is lost in the IR 'dazzle' from the sun.

is there any way of telling the difference between ir fob and rf fob regards les

[xantia_v6]

IR fob with obvious big rubber buttons (also has IR LED on front)

RF fob has small rubber buttons just laong top edge (and no IR LED)
