if you have had your locks playing up after rain or what ever
i spent months thinking that they where stuffed until one day i just pulled off the panels and sprayed wd40 on the locking mechanism and hey presto instant fix. i thought i was going to have to replace all the locks because of them not locking right but there still good hopes this helps
nar this is advise because iv fixed my problem by doing this haha
