XJS facelift 4.0l 1993 60K.
Car standing for couple of years doors apparently deadlocked.
AA gave up after half a day
Auto Locksmiths [two of] made new keys no joy gave up and went away [no bill to pay as unsuccessful].
Boot lock broke after much offort so access to boot , new battery..nothing happening.
Door mirrors off managed to move door lock 'paddles' both sides to 'unlock', nothing.
Suggested removal of front screen but how to access locks with removing door panel?
Drill out door handle seems drastic but feasible action.
Your thoughts suggestions ideas much welcome.
