I just has a flat battery and there could not gain entry. The drivers door manual lock would not allow entry also. After breaking back window to gain entry, recharged battery, re-coded fobs, but manual lock still does not work. Any suggestions? :mrgreen:

Hi Cqrobyn

The first thing I'd try is lubrication in the lock barrel. Graphite based penetrating fluid in an aerosol is ideal but WD-40 type products will do if you don't have any graphite based. Spray inside the lock barrel, leave it for a few minutes and then try gently turning the key left and right. Repeat as required. If the lock is still absolutely solid it could be that either lock or key have been changed.

If the key turns in the lock and nothing happens, check that the key is turning far enough ie 90 degrees. If the lock barrel seems OK then my next step would be to look inside the door.

If lubrication works and you've used WD-40 I would get some graphite lubricant as soon as, WD-40 is good but unless you repeatedly apply it will dry out and eventually set.
If at first you don't succeed, destroy all the evidence and pretend you never tried :lol:
