What can I do about sloppy locks

[badgerfax]

My drivers door lock is pretty sloppy, the passenger lock isn't too bad. The slider lock does not work at all and has to be operated from inside & the tailgate is on a separate key and is like stirring porridge.

Ideally i'd like 1 key to do all the locks but am ok with leaving the ignition alone.

I have read about retumbling but not sure that would sort out the sloppiness. Do I need a new set of locks then retumble to 1 new key

Any ideas

its the part the lock internals register to that is ally and wears over time so sorting the key issues will have no effect on this, get a new set s/hand may also be sloppy or dig d££p

You need a new lock, then change tumblers in it to suit your key. In most cases this only applies to drivers door which gets most wear.

My driver door lock is a bit sloppy.
I have decided to always let myself in through the passenger side.
That way I will gradually even up the wear on the locks (and the floor mats)
Only 22 more years to go until I start letting myself in through the slider...
