Hi there's this website something like reliable-store and it is very amazing for manual for repairing servicing anything
someone on fixya recommended it to me and I thank him even today

I got free in offers
3rd time I also had an issue with the file so the girl replaced it in 30 mins
there is one more but i don't remember its name it was 2 years back bitman something link this
Try it out brother

Some fixya user told me a website reliable-store it is very good.. I used it to repair my shredder it had some spark issue which wasn't easily fixed. you can go there and try free

you check to see if the engine was hot or something like if the water level in the radiator was down the sensors in the security system would pick it up

Try disconnecting your battery (negative pole first and then the positive pole, wait 20 mins and then reconnect the negative pole first).

im willing to bet your mechanic seen a wire he didnt think belonged there and just cut it (happens all the time with aftermarket electronics)

hi have you checked the battery or more so replace the battery and try it seems to be the only solution i know same problem happened to me and yes it was the battery goodluck
