Doors Lock Automatically When Connecting Battery Cables

[RAGING FIRE]

WHEN I CONNECT THE TERMINALS ON MY 1993 ES 300 THE DOORS AUTOMATICALLY LOCK...........THEN WHEN I TRY STARTING IT THE ENGINE TURNS BUT IT WONT START. IF I TRY TO REMOVE THE BATTERY TERMINALS I AM UNABLE TO BECAUSE THEY'VE ACQUIRED A HEATED TEMPERATURE.............IF ANY ONE KNOWS HOW I COULD RESOLVE THIS ISSUE PLEASE HELP ME OUT. THANK YOU :)
