Somehow my security system is getting turned on, I guess by itself? Anyway the system is locked and trying the lock then unlock has not worked. What to do now?

 

I would pull the battery + wire and let it sit for 10-20 minutes to reset the system. I cannot find anyone with a Civic/Fit with this issue on a quick Ooogle search.

 

Thanks for the reply and sorry for not responding sooner. I didn't need to use the FIT until yesterday.The FOB didn;t work and had to use the key to manually open the door. Checking the battery cables I noticed the +cable was loose moved it till it stuck on the post... tried the fob and the car locked and unlocked and most important started up. A few months ago I had a trickle charger installed because the FIT battery is a piece of crap and if I let the FIT sit for more than 4 days the battery is dead. I'm guessing that the nut that tightens the cable wan't tight enough and worked itself loose. Anyway it works, Thanks!

 

Good to hear that you're back on the road.

 

My Fit frequently sits for a week at a time and I never have a problem with the battery. I do clean and re-tighten the battery terminals every summer and when I am driving it it's on highway trips which do charge it up nicely.

 

I should have added - during the COLD months.
