Automatic Gate Lock (FM143) for Mighty Mule Automatic Gate Openers , Black

Works great, installed easily on my farm gate. Very heavy duty lock.

A direct lightning strike took out our original 6 year old gate lock. It worked flawlessly, so we purchased another one. So far, so good. Easy installation, I think a little pricey, but when you consider my family’s safety and the security of our farm’s entrance, I guess it is worth it.If you have a Mighty Mule automatic gate opener, you need an automatic gate lock.

Someone decided they needed to be on my property despite the gate, fence, barbed wire, and two retarded dogs. After I came home and saw my gate bent open I decided this was no longer too expensive to get. This has two wires that you have to figure out how to get to the black box. Once you open up the black box you can stab around pretty blindly and still hook this up pretty easily. I am a complete goober and managed to make it work! Believe it or not, it makes a notable difference in the (false) sense of security you have with a gate. It makes a person have to WANT to come on to your property instead of just pushing the gate until it yields. It will NOT yield with this in place. Your gate will physically break before this gives out. It is very solid BUT dependent greatly on your method of connecting it to your gate. I did not use their hardware. Instead, I used two "U" bolts that lined up perfectly with the holes and then "fixed" the nuts so they would not easily come off. All in all, I am very happy with this lock. It works great.

Overall the gate lock works well. It seems though that it has made my controllers connectivity a lot shorter; I used to be able to stand at my door (about 75 feet) and open my gate but now I have to be within probably 20 feet from the control box for it to activate. I had to custom make a plate/instation bracket for the auto lock assembly but I have a small 110v mig welder so that wasn’t really an issue - just had to buy a length of flat 2” steel, cut it about 5.5” and spot welded it together. After that I fully welded the plate in place and painted it. I just drilled holes and bolted it on as I didn’t want anything too permanent incase it failed to operate and I need to remove it easier. After mounting it the wiring was easy just two wires into the control board black and red. It unlocks a split second before the gate activates - very smart programming there! Works great!Now the bad and why it only gets 4 stars... I can pick this lock in about 10 seconds!!! The latch mechanism inside the can be pushed in to unlatch the catch! All you need is a thin flathead screwdriver and voila! Your gate is unlocked-open! Not real happy about that for over $100! So it’s not a real “security” lock. It’s more to keep the gate from blowing open when there’s a little “slack” between the closed position of the motor. It is a good trapasser deterant though. Besides - if a thief or trespasser really wants on your property they’re going to get in one way or another. Thanks for reading.

This gate lock turned out to be an awesome buy and works as intended!Where I work, we had to install a hydraulic arm with remote control to open/close the pool gate for someone in a wheelchair. Even with the gate closed, you could still push the gate open about 2-3 inches. We were concerned that someone could shoulder the gate open and break the hydraulic arm. I ordered this automatic gate lock and had it hooked up to the hydraulic arm for added security/safety. It works perfectly!! When the remote is pressed to open the gate, the lock disengages and the gate opens. When the remote is pressed again, the gate closes and the lock engages. The gate is now very secure and we do not have to worry about someone breaking the hydraulic arm.To me, the item is listed at a fair price. I would have paid more for this automatic gate lock.

I purchased the gate opener for our 16’ aluminum gate but then I read some of the reviews for the opener that said your gate could still be pushed open with a strong gust of wind so I got this. When I purchased I thought the key only locked the gate if you got out of your car and manually locked it. Good surprise it locks automatically and the key is only for emergencies if your gate won’t open electronically. Since my primary purpose for purchasing this was for ensuring the gate latched and couldn’t be pushed or blown open I am VERY happy with it. I didn’t get it for security because looking at it you can tell it isn’t a great lock but I don’t expect to get broken into either. We prefer to close the gate when we are out but I don’t like spending all the time getting ready in the morning only to have get out on a rainy day and manually shut and lock the gate when i go to work or come home.

This Mighty Mule Gate lock replaced original lock which lasted a dozen years. It works well and is robust. The lock stops folks from pushing on closed gate and breaking the power operator and/or mounting brackets.

$138 and no mounting hardware. Couldn't include a handful of bolts! Digital instructions? Seriously, print a sheet and put it in the box!!
