After replacing alternator the radio and power locks are not working

This is very common, but not due to replacing the generator. It's because the procedure starts with disconnecting the negative battery cable. When the battery is reconnected, numerous computers cause current surges when charging their memory circuits. That often causes multiple fuses to blow.

These diagrams show the locations of the two fuse boxes. For the radio, check fuse # 10 under the dash, and fuse # 35 under the hood. For the power locks, check fuse # 24 under the dash. The second one is fuse "D" under the hood. That is a 40-amp fuse so it's not likely to blow in this case.
