156: Keylock electronics malfunctioning

Hi,



A few weeks ago, for the first time in 7 years, my 156 wont start. After
inspection, it was clear that the keylock electronics were malfunctioning.
The yellow coloured keysymbol in the central display doesn't light up at
all, prior to starting the engine (were it should normally light up for just
a second). The service manual only mentions a continues lighting keysymbol,
indicating an error on this feature.



Locking, unlocking didn't help; neither did a new insertion of the key.
Using the 2nd (spare) key also didn't help.



Desperately I started to try to execute the emergency procedures, by using
the throttle pedal (10s) and flashing red injection indicator in the right
display, as tools for a sort of 'manual' input of the keylock code.



A few weeks ago this stops the error, even after not finishing the entire
procedure!

Yesterday, it didn't help at all.



Anybody any idea to recover from such an error, or maybe it is a known
hidden feature ???



Thanks in advance for your reactions.

Unlocking by using the gas throttle tools (full code input) helps this
morning.
The fuse btw is also ok.
Seems to me that the electronics or the antenna is causing the error.

Stupid question I know, but have you tried replacing the battery in
the key?

Stupid answer, I know.
The battery is only for the remote control, which functions well.
The electronic keylock code is powered by the antenna near the key insert. A
coil on the circuit in the key is picking up this signal, and uses this for
powering its electronics and transmitting its code.

Nice guess anyway ...
I'm afraid it is the immobiliser!

Hi all, I too am experiencing difficulty in starting my 156. I have owned
it for 2 weeks and sometimes when i try to start her the yellow key symbol
stays lit. After leaving it for a minute or two it works. Does anyone have
any suggestions?
