Lock problem with my ford

hey i have my Ford YT16 and i'm facing problem with my door lock. it's locks will not fully lock or unlock using remote or key pad. This issue started when temperature dropped at start of winter I thought as temperature increased locks would start to work but now this issue getting worst day by day. so if anyone knows about the best locksmith
suggest me about it.

sounds like poor electrical contacts either in a connector or ground tab. If you can get into the connectors unplug and plug them back in. Oxidation from water will give you all sorts of funky happenings.
