Can't get into vehicle! Sign In

1986
Mercury Cougar
V6 engine

So I can't get into my vehicle. When I put the key in to unlock I felt a pop followed by the lock moving free but not unlocking the door. Same thing on the passenger side. I have power locks and the silver knob that goes up and down but the battery has been dead for at least a year. I used a slim Jim and got the knob to raise thinking I had succeeded bit the door was still locked. Has anyone ever dealt with a broken locking mechanism, dead battery and Sim Jim not working? Really don't want to bust a window and get a replacement for $175 unless it's completely necessary.

You are going to have to get the hood open and charge the battery.

Unfortunately when and if a power lock motor fails frozen in this vintage of Fords the rod will prevent key or manual function at the latches. Tough but need to get inside and unhook those rods if so or break off unseen somehow with a slim jim type something.


Not fun. Sitting can cause this as it did. Just a maybe as taking off a door panel of a closed doors is most difficult and worse if you can't get inside I'd bet you'll be breaking something else to even get to things for a fix,

From what he has described, the linkage has fallen off the key cylinder. The only thing preventing him from unlocking the door electronically is the dead battery.

Then why doesn't the key work? Then can open hood and deal with battery.


The lock motor on these do freeze. Rod is like a twist of licorice and as motor turns if and when done manually it still moves but if motor doesn't move manually it stays locked and unless rod bends enough you are screwed! Not safe but they did that, that way. Nasty as a key will break before rod bends in most.


Some I've sprayed thru any gap in door jams and down thru closed window rubber but need to be lucky to hit right spots and lucky if that works. Rods are not on outside of inside metal but in between panel and metal.


Personally never had a two door with both doing this. Once inside car there are more options. Motor IF FROZEN will NOT move nor the rod you must bend or break it.


There's a crap rubber boot to keep moisture and water out of the lock motor that is never intact years younger than this.


Need a good junkyard with some 4 door as the plastic holder for motor will probably break too when that far but once rod is removed manual knob or key will work lock unless latch is also messed up.


You can put or get longer rods if you can't get old ones out and just bend/cut but keep the spiral licorice part being way too careful not to loose the 3 little perhaps 1.5mm side balls that ride them up and down the spiral making a turning motor make a rod do the push pull thing. Common as all get out and plain unsafe design,

(EDITED as it's confusing to describe) Motor actuator looks like this whole.........



Unseen and unavailable is new rods. Pic doesn't show the spiral and balls that ride the channel held by that tiny ring which is held by a small push clip. The rod must turn the motor or rod can't move! That's a common issue. Fix is either disconnect the rod and just use key or manually inside OR replace the motor (hard to find with correct rod and can use a good old one sometimes) but absolutely will prevent door from either locking or unlocking if frozen up. Again - motor turns all the time battery or not when this thing must move! That's common. That rubber raincoat is useless as said and doesn't last 10 years never mind this vehicle. They do keep working if used all the time - Arggh! )
