central locking issue

[baldy1]

Just acquired van last few days and slowly going through extensive list of issues..
1st on list central locking in presuming this is down to bad maintenance or damge
when you lock the door(s) all c/l activates doors lock then unlock .
.could this be down to damage the age of van or remove c/l and modify rear and side loader ?
