Lots of Daewoo's have Inertia switches fitted, if non-start and central locking not working, the inertia switch might have tripped, it could be under either front seat or bonnet.
If the remote fob won't work, try re-synchronising by unlocking car with key, then turn the ignition on and off, then immediately press one of the fob buttons 3 times it should now be re-synchronised.
