You say Autoloc brand, not their solenoids specifically...so it sounds like you have limited experience with their shaved-door kits. The solenoids are garbage. The metal-on-metal design is bad, period. I would not recommend any given brand; Autoloc just takes their generic remote kit, throws a couple of solenoids into the box, and gives poor directions for the consumer to figure out. Buy the kit with an alarm, and they just toss the generic alarm kit into the box as well. I can do that on my own with better components. Their warranty is bogus, which I tried to cash in on less than a year after purchase. Their customer support is poor, if you ever get through to them. There is nothing about that company I would support.
If I were to do it again, I would piece it together on my own. I had to buy my own relays and wiring for it anyway. Get a decent remote kit, then add decent solenoids to it and wire accordingly.
Here is what the Autoloc units look like:
And what I replaced them with after they seized in under a year:
The dew-wipes were brand new on the vehicle when I installed the Autoloc kit. One winter season wiped out the solenoids. The ones I replaced them with have been going strong, in the same weather conditions, for six or seven years now. There will always be a small amount of moisture that makes it into a door, and that is all it takes to kill an Autoloc solenoid. My 2¢.
