Porsche Boxter 2002 CDR-220 Radio Code [SOLVED!]

Trying to unlock neighbor's 2002 Boxster radio, left battery dead.

Car VIN: WP0CA29862U621527

Radio type 4462 (model CDR-220, Becker)
Radio S/N: 15064969

Unlock code he has is 1053 but he has tried many times. Radio is currently in WAIT mode and I'll try after 1 hour.

Thanks.
