This answer assumes there was no starting problems or battery light or check engine light or alternator lights on before the maintenance work or your visit to Mr advanced.

Most likely the connection where Mr Advanced spliced the new cable to the old is not strong enough to conduct the 150 amps needed to crank the engine, but is strong enough to conduct the 20 - 30 amps needed to run the lights, etc.

It may be possible to start the car by gently re positioning the spliced area so the new and old wires make better contact and then trying the key.
If it works, it probably won't work more than once or twice so be ready to go back to visit Mr Advanced.

Splicing in a battery cable to an old one is a pretty uncommon repair. Replacing the end of the cable that clamps to the battery is common. Replacing the entire cable is a common repair.

it is also possible that your car is not in park/neutral, the anti-theft needs to be disarmed using the remote door lock opener on your keys or the new battery is defective.

Hope that helps,
