Technical DOBLO immobiliser key

[birnieaskew]

Hi , a friend has an immobiliser key which has a loose chip. We are going to resolder it but could do with a photo of a working one (we dont know which way it goes in?)
Can anyone help with an internal photo? thanks in anticipation

Hi Ian, Welcome to the FF.

Most integrated circuits have a mark on one corner and a corresponding mark on the PCB for orientation.

I may be wrong but I thought all of these ID48 chips were glass tubes.

Agree... the ID48 transponder is in a glass tube but as the OP referred to soldering I assume he means the IC on the PCB.

seeing this thred i thoughti might bring this up, ive got the key and inside is the glass tube. right heres my problem i think...

The glass tube appears to be broken. In Fact. IT IS! ive got no problems and ive only just noticed it as i has to use the key to open the door and the key just opened itself up. i must say i have not put the key in the door for nearly 4 years...!! A BIT STIFF! :slayer:

anybody think that could cause me a problem??


OVER AND OUT"! :worship:

sorted!
The chips were all ok it was (i guess) an inductor on the rear
Cleaned pcb ,soldered worked perfectly

Your going to have problems starting the car if the glass is broken.
Give the barrels a squirt of silicon/teflon spray.
