I have recently been having problems with my car starting and then cutting out a few seconds afterwards. I have plugged in a code reader and it gave the following error codes:

17975
Engine start blocked by immobiliser P1570
Static- no indication on display

01383
KWP1281 Alarm triggered by anti-thief system front right
Static- no indication on display

I am assuming it has something to do with the immobiliser system with the alarm having nothing to do with it. I have read lots of posts but I do not get the flashing immo light, it comes on and turns off after a few seconds from starting the ignition. I have taken it to a garage who think it is the instrument cluster that needs replacing. It intermittently works and seems to start more often if the key has been in the ignition for 10-15 mins before trying. I have the SKC number, would it be possible to temporally/permanently disable it? I only have one key and one workshop key with the tag.

Any suggestions would be much appreciated.
