im sure some of the other integra out there do this, or have had this happen..... and if not yet then this is what you have to look forward to. both of my integras a 96 db7 and a 94 gsr,
the key to unlock the door from the outside when its cold out will not let me in and if i get it in, it will not let me turn the key. what causes this, how do i fix it? in the previous winters i have just put hot water on it and it lets me right in, but then that just freezes later and its a big circle of crap.

Also on my 2door when i unlock it sometimes the lock motor goes crazy, like a lot of clicking.

WHAT DO I DO?

 

for the key issue, from working at honda we had a clear grease we would put on the key and then put into the cylinder to relube it and usually fixed the issue.
the lock going crazy is because the motor is getting jammed somehow. rod needs grease and is sticking, just one suggestion
