Toyota Duet 2003 problem

Good I am new in the forum, above all, good information page, but unfortunately what brings me here is a problem that I had with my automatic 2003 Toyota Duet 2003, a few days ago thieves stole the radio from my car, violating the chapa of the car door and leaving several loose cables that connected to the radio, without much knowledge my parents took the car to a workshop to which they place a new radio, but the detail is When I came to the house I found the surprise that the car starts, advances a few meters and when making the automatic change to second, we went to a specialist technician and the radio withdrawal, scanned the CPU of the car, the immobilizer and has told us that it is probably a problem of memory, I do not know if they can help me clear that doubt if that or else is that or something else. Thanks in advance

If, when stealing the radio, a short circuit is made, the most caused is that the computer has the immobilizer or the anti theft activated, according to your model, on occasion they walk a couple of blocks and stop because they are put in a state of emergency, and if you want with a computer formatting, you could try, you could try to disconnect the battery to see what happens.
