The lock button on my car key fob hasn’t been working for ~ 6 months. I was looking at buying a new key fob for between $9 to $35, but something told me to take it apart.
Some isopropyl alcohol, a used toothbrush, and 5 minutes later I discovered some kind of sticky blue goop had infiltrated my key fob. After a quick brush down and slight emersion of the lock button, my key fob is now working again.
My 99 civic Shela (can drink and rent it’s own car) has a key fob that works but all of the actuators for the locks are busted. Have no fear though, the windows still roll down…I just have to crank it myself because Shela is a golden girl who only deserves the best.
