hi have a problem with my upvc door. its been locked now i cannot open it, it hasent been used for some years now. never had to use because it on the garage but want to use now after a spat of crime in the area. i have the key and when i turn the key it turns to the point just before it should unlock the door then stops. i can turn the key both ways. ive put WD40 in the key hole but still no luck. ive tried lifting the door when turning still no luck. ive been told that the look may need to be drilled out, if i do drill the barrel will it come out and then unlock the door.
please help
