Product Description

1979-1993 Mustang Door Lock Actuators
So your key won't turn in the door, the lock knob won't push down, & nothing happens when you push the lock button? Well, it sounds like you need to replace that bunk door lock actuator! Don't worry door lock actuator failure is a common occurrence in 79-93 Mustangs.

Actuator Failure
There are a few ways to determine if your Mustang door lock actuator has stopped working. The first way is that the key still works in the door but nothing happens when you hit the unlock button. Or if the key won't turn in the door, the door lock knob is frozen in the unlock position & nothing happens when you hit the switch.

5 Stars   Good stuff
By on 7/14/2016
Part fit perfect! LMR install video doesn't really explain where the push bar goes. There's a yellow hole that can barely be seen that it goes up through. I had to take my passenger panel off just to make sure where it exactly went. My advice would be to check both sides so you can just order both,unless you bought the pair. Also it may be easier just to slide the old actuator out of the bracket and slide the new one in!
Thanks Lmr!

5 Stars   works exactly as it should!!

Not sure how people could not get this to work / claimed it inferior to the OEM. Well it works just as good as the OEM. Install is pretty straight forward but not without a few quirks one would benefit from being aware of. The fiber board door panel removal was the worst so have some superglue for board repair around where the trees go and extra trees because they break easy with old age. A hair dryer works well for easy pealing back of the vapor barrier without melting it or ripping the plastic (just go slow and don't overheat). The Drilling out of the OEM rivet was a bit of a pain as the center is hardened steel. Just have a sharp drill bit mated with a powerful capable drill to get it removed ( !!!be very careful / steady with it and do not rush!!! ). Have a vac handy for all the metal shards you will be creating. It is a bit awkward holding the unit while trying to rivet so I took some shop rags and pressed them in locations within the door to help hold it temporarily in place while being perfectly aligned with the hole for the rivet install (you need both hands for the rivet tool ). My install was on the passenger side door of my cherry 93 cobra.

I purchased this because the actuator had seized up on the driver's door of my 91 GT, and I could not lock the door at all. Once installed, the actuator would not work properly for a while and I thought I had received a defective part. However, just as others have said, it does have to be "broken in". I kept manually locking and unlocking the door with the key, and I sprayed lubricating oil onto the lock rods, as they do have a little age on them, Lol. Just as I thought it was a lost cause, they began to operate properly and have been working flawlessly ever since. I am very happy with the part. It locks and unlocks like a new car now. Very pleased.

I struggled with my dead actuator for several months now. I finally purchased this for my driver's door the other day. It arrived quickly to PA. I installed it tonight. I probably had about an hour or so into it. I did not have a rivet tool, so I wanted to reuse the original metal frame. I pried the old metal frame with a long screwdriver to open it up a bit. Then I managed to twist the old actuator out. The side pins came out of the rubber barrel washers. Those rubber washers remained in the metal frame. I then used a small screwdriver to pry out the old rubber washers from the metal frame. The new actuator with it's new rubber washers seemed to install into the original metal frame without too much drama. I had to get pressure on the actuator from the bottom and work it back & forth / up & down, but the new rubber washers slid into the metal frame OK. Maybe a bit of grease or oil on the OD of the rubber washers would make it go easier yet. Use a door panel removal tool and install new plastic push-pins. That will save damage to your door panel.

I guess I got lucky and got a good one outta the box. Hooked mine up and it immedietly worked as it is supposed to. I had a plan if it didn't work and needed to be "broken in". Hook it directly to the battery with wires and let it cycle forward and backward a few times. I actually got my old dead one to work again with some WD40 and hooking it to the battery and just letting the actuator run and run. Now I have a spare. I thought it was cool they actually send a new rivet which worked in my standard rivet gun. It was tough but it worked.

3 Stars   New door lock actuators
By on 8/6/2016
I bought my 92 LX convertible new and have enjoyed driving it for the past 24 years. About 17 years ago the lock actuator on the passenger door quit working. I have been making repairs to the interior this year so I decided to replace both actuators while I had the door panels off. The new actuators went on just like the video showed me the only problem is there were no rivets in the box and I am having a hard tie finding a rivet locally to complete the install, Any chance you can send two rivets so I can get the door panels back on??

1 Stars   Weak motors
By on 10/31/2014
I bought these for my 89 5.0 LX Restoration. With NOS door latches and all NOS parts, these motors are not strong enough to move the tighter NOS parts. LMR says you have to break them in but after about 50 times or more they didn't feel any better. Found FORD NOS door lock motors and they worked perfectly, sometimes what you pay for is what you get. Its like their window motors, they should list not strong enough for T-Top and convertible cars.

4 Stars   89 Mustang GT door lock actuator
By on 6/10/2014
Item arrived well packaged and was installed and works fine. Only problem with replacing this part is the size of the rivet that comes with it. The typical rivet gun everyone has around the house will not work due to the size and you'll need to either borrow or purchase a professional rivet gun. My mechanic had one at his shop and helped install the rivet while one of us held the bracket on the inside of the door.

The first actuator i bought was really weak and didn't lock and unlock the door.
I called Late Model Restoration and they sent me a new one with no hassle. I installed it. I works a little better than the first one at this time, but not as good and the original before it went out. I will give it some time to (break in). Time will tell.
BTW I have locked and unlocked it dozens of times (cycles), not 10 or 12..

I purchased this kit in March of 2013. Went for a ride yesterday and now my passenger side door won't lock. I honestly expected this replacement to last longer than 3 years considering the stock components lasted 19 years. Never had a problem with this company and will still buy from LMR, just a little disappointed in this product. They have a one year warranty for a reason on this product.

I just bought my '89 GT out of a barn! and the original lock actuator had rusted solid due to non-use. I was able to pull the Ford unit out of the factory bracket and using the new rubber isolators, the new actuator was installed. It took a bit of muscle and some careful bending of the bracket to sneak the mounting pins to place. I'm glad I didn't have to replace the bracket itself.

Perfect replacement lock actuator. Gives a strong lock and unlock pulse. Install tip: fill up the inside of the top weather boot with white grease to keep the shaft lubed and help with extra weather resistance. My first set locked up from corrosion in one year of time. LRS was excellent help when my first set did fail and gave me a new set for free.

5 Stars   Like OEM quality
By on 10/31/2014
Bought just the passenger side. When using my power locks, the lock plunger would not go up or down without manually helping it. Lubing the original lasted a year before replacing the unit. The driver side is still strong, probably because I don't use the power locks much ( only unlocking the driver side by the key).

By on 11/26/2014
I live in San Antonio so my parts arrive in two days. Reviewed the install video, parts went in just as the video shows. Actuators seem a little weak but I've only had them installed for a week now. Maybe after they get "broken in" they will work more smoothly. Good product though especially for the price .

1 Stars   Weak
By on 4/7/2014
Actuator is too weak to lock or unlock the door without manual assistance. Really don't want to disassemble the door again to remove and return it. After I had purchased the product and installed I had read other reviews all with the same problem. LRS really should find a new manufacture for this product.
From LMR.com: The actuators are very "tight" for the first several cycles. They do start to "beak-in" and will function normally after 10-12 cycles.

Bought these to replace old ones and was a little disappointed.looks great and fits great but as other guy said.dont seem to work unless you manually force the locks to operate.being new I would expect to install operate properly and not have to (break in).i rate it. 1 of 5....1 for the looks
From LMR.com: After cycling the actuator manually a few times it works like a charm.

1 Stars   Too weak to actuate lock
By on 9/13/2014
The actuator moves up and down when I plugged it into the harness without installing it in the door. When installed in the door it doesn't have the power to move the lock. Too bad I waited so long to install it otherwise I would have asked for a replacement.
From LMR.com: We apologize that you had a problem with this actuator. Please expect a call from a customer service representative on the issue shortly to get it resolved.

2 Stars   lock actuators 1989 GT
By on 5/31/2014
Part looked great but not as easy to install as the video indicates especially when dealing with the rivet. Had hoped to reuse the current bracket that holds the actuator but it seems that it was broken when the car was made as I'm the original owner and the old actuator was held in place with a plastic tie clip and one of the curved brackets broken. So had to remove the rivet to remove the bracket - fine but to have to purchase a special rivet tool to install the rivet is ridiculous. I have 3 rivet guns and the rivet provided does not fit in any of them. So, currently looking for a shop or person that has the right size just to install the rivet to hold the bracket so the lock works.

By on 5/19/2014
If you actually want your locks to work don't bother with this.

It is so weak that it won't unlock or lock the door.

It did spin up and down freely when I connected and tested it, but once put on the actual lock mechanism it did not work at all. It barely bumped the lock but never fully unlocked or locked the door.

I found an OEM actuator on Ebay thankfully and bought that (of course it was $150 bucks so you do indeed get what you pay for) the OEM actuator works perfectly.
From LMR.com: After cycling the actuator manually a few times it works like a charm.

I bought this to replace my broken stock actuator in my 90 LX. After reading reviews I was hesitant because of issues with sticking. Well, after 4 months it still sticks. Went from needing 12-15 presses to 2-4 now. Not sure if actuator or lock. Either way a must have.
