W203 - key- circuit - capacitor "knocked off" - value needed

[mikegough]

Hi all
I have a problem with my spare key
It unlocks the doors& boot
it Will not start the car unless I press lock with Key in ignition, then car will start but most instrument details are not operational

I investigated and identified that a capacitor has been knocked off the key as per diagram below - does anyone know the value of that capacitor

I just looked at an old key I have. It is not exactly that layout, unfortunately. There is a similar looking component in a vaguely similar position, but it has no markings.

However, I do not fathom how it could be accidentally "knocked off". It's lower profile than surrounding components, and is very securely soldered to the PCB.

Hiya JohnArnoldBrown ,
thanks for looking for one for me , I got the car 2nd hand with a 'dodgy' 2nd key the plastic case was in V bad shape and I assume something pinged it through the holes where the buttons were
