I have a 97 mustang .. so I had a friend come by and delete my check engine light due to the O2 sensor..once he finished I tried starting the car but I noticed the "Theft" light came on blinking fast.. I have no idea how the key Chip ended up getting dis programmed.. any one in San Jose area now how to fix or reprogram it

Search online for an at home fix. Might just be something real simple

you have to call a lock smith and have them come out and reprogram it

also check all your fuses in the fuse block under the hood first
