Hello All
I have a 97 accord with power locks, I had an Alpine sec100s alarm installed and found out that my powerlocks don't work properly.
Doors unlock using keyless entry and by using the unlock switch inside the car, but it wont lock by neither.
It will lock by pushing the lock button (not the rocker switch) from the inside once all doors are closed, as well as by locking from the outside using the key.

The alram installer told me that it might be a broken relay somewhere.
does anyone have an idea as to how to fix this?¿

 

do you think there's a couple of relays used for the powerlocks? one to open one to lock it?¿
