Previously Replaced Car Lock Causing Problems - Easy fix?

The drivers door in my car has obviously been replaced at some point, as to open it you turn the key left, whereas on the boot and the passenger side, you open by turning the key right.

Also, the keyfob remote will not control the drivers door, but does the passenger door.

I've lived with the problem for a few yrs now, and its not been an issue, but I am considering an upgrade at some point this year, so ideally want to get this sorted to maximise its PX value.

Anyone have an idea what the problem is? Could it be a simple case of switching over 2 wires attached to the lock, or is it much more complex?

I have asked one garage, but they say they dont know what the problem is and want to bring it in for chargeable diagnostics, which is about £60 an hr! Of course, it could turn out to be very little, and they may be honest about it. However, they may instead take me for a ride, so id prefer to get some thoughts from others before taking it in!!!

Any ideas, recommendations, or even suggestionf of anything I could do to help diagnose it myself?

The key operation can some times be as described, my old Toyota door key locks worked this way

The problem with the remote opening could vary from a loose or bad connection, the wiring can be snapped due to opening closing the driver door a million times or a failed electrical lock mechanism inside the door it self.

If its a "old" car soon to be rid of is it worth the effort?

my fiesta is similar, in the way the lock barrells work,
I remember it by thinking 'turn the key back (to the rear of car) to go forward' (drive)
and forward (towards the front) to lock.
Think most cars are like this?? doubt any prospective buyer would be put off by it (if they even notice).
Regarding central locking,as the previous poster said,it could be a dodgy connection,or you might need an actuator,cheap enough from a scrappy,but doubt a dealer would source parts from there.
Sometimes taking the door card (interior trim panel) off & a wee squirt of WD40 can help.
If your not confident to do that yourself,i would steer clear of putting it into a dealer for a fix though,as the opportunity to rip you off may be too much for some to resist (no offence to any legit mechanics reading this thread).
If i couldnt fix it myself,i would just be honest with any prospective buyer,and tell them its not a big deal,the drivers side works fine. Good luck

Are you saying your cars are like this too??? Seems strange for them to be like that new....

Just to clarify - the passenger lock and boot lock are unlocked by turning the key clockwise. The driver door is unlocked by turning anti-clockwise.

On my partners car all doors unlock anti-clockwise, and lock clockwise.

The car is 7 yrs old now, and otherwise runs well. It should sell for ~£2000 with the problem fixed, but i think not fixing it would put buyers off. Im not going to deceive anyone - id tell them of the fault if I didnt fix it!!

nope twice I've read it & i cant see any mention of the make & model of the vehicle :thinking:

hi rich - its a hyundai coupe (newer 2002 onward design, not the smaller, older version)

Yes my door locks operate like yours,it was gf's last car that had a sticky solenoid on passenger side, i got parts from scrappy to fix it,but when i had the door apart i found that WD40 did the trick.:thumbsup:

Interesting! How did you know where, and what, to spray??

In best Haynes manual style
1 Remove inner door panel :whistling:

2 Remove plastic sealer skin

3 Locate door lock solenoid (part with wires going to it and linkage to lock) spray moving parts with WD 40 work parts to free off any stiffness and test with remote control.

Do you really think anybody is going to notice or care when you PX this … Do you really think anybody is going to notice or care when you PX this car.Just leave it and forget about it. :thumbsup:



Im pretty sure if PX'd the garage would care, and if sold privately the buyer would care :thumbsup:

Don't some cars also have instructions like "Turn the key to the rear of … Don't some cars also have instructions like "Turn the key to the rear of the car to lock" ?This would mean clockwise on one side and anti-clockwise on the other. :thumbsup:



Thats [good] news to me if correct - cant say ive ever consulted the manual about how to use the locks before!!....will have a look today!

Yeah,go check the drivers handbook,shame you dont have a mate with a similar car,
(or ask at a dealers what the 'normal'operation is).
I dont see how replacing the lock barrell would affect operation (direction you turn the key) myself as the barrell will only fit in one way up?.
Pretty sure your worrying over nothing.
if you had to replace just one lock barrell,it wouldnt be too expensive,but the chances of getting one to match your existing key are slim.any dealer is much more likely to try and convince you to replace them all (@ 3x the price).
It would take more than a sticky door lock/slow solenoid to put me off buying a car i liked,though i cant argue that i wouldnt perhaps moan about it in an effort to haggle the price down.:p
I'd be surprised if a dealer would notice though,until too late i.e.you'd traded it in and he was trying to sell it on to an ultra picky 2nd hand buyer (like me);-)

doubt if a garage would check the car in that much detail and notice. Most PX cars just get sent to auction. It really isnt worth the hassle / expense.

Doubt a private buyer would notice either.
