Hi Guys,
I'm new to this forum so please be gentle with me, I recently bought a Focus that's been well looked after, however the guy I bought it off said the car only locks from the key as the remote key battery died and disabled the remote locking. A couple of days ago I read how to reprogram the key which I did and it's been working perfectly, up until today when I came to lock the car, not matter how many times I pressed the lock button the car unlocked itself, eventually I managed to lock the car from the key, However when I lock the car the front passenger door will not lock but the other 3 will.

Can anyone shed some light on the subject, and suggest a solution without having to go and spend a small fortune at the auto electricians or Ford themselves. Also If I remove and replace the battery from the keyfob will it forget the code

Thanks in advance for any response.

Hi, how did you reprogramme the key? My mate has the same problem with his Focus.

Martsford

Hi
I read to reprogram the key you do the following:
put the key in the ignition and turn from I to II 4 times within 6 seconds, the car will chime twice. Then press any button on the key fob.

This should work as it did with mine but now I have the problem of only 3 of the 4 doors locking and unlocking.

JayCC

I'll give it a go tomorrow and let you know if we have the same issue. Thanks for the heads up!

Martsford

Yeh Please do,

I read something along the lines of having to disconnect the power from the control module to reset it. It lives above the accelerator pedal, but do your own google research first.

I presume you mean the passenger door won't lock remotely, but it will by key?

mine did same and then my drives door mech packed up

my focus does this when the temperature drops
in the summer it works fine, it is supposed to be a small part on the drivers lock that has is playing up
mine locks fine from the passenger door lock but will not lock from the remote or from the drivers door

If it locks with the key, it maybe that lock needs lubrication (As should be frequently done anyway, along with hinges etc)

Yeh that's exactly right Martin, the door will not remotely lock, I've been to see a auto electrician today and he was very sure it was a fault with the door latch on the passenger front. I don't know anything about car electrics, so wouldn't know if this was in fact the problem or whether it was just weather related. I'm thinking i may whip the door card off as the weekend and have a look at the latch itself and make sure there's no loose wires.

Also just for clarity, the doors would all run off 1 fuse wouldn't they and not a separate fuse for each door? (like I said I don't know much about car electrics)

Yes, that being fuse number 63, you clearly don't have a power issue by the fact it works fine with the key.

Martin

Martsford

Would you agree with the diagnosis of a faulty door latch as the problem?

martysmartie

Not really, because it locks with the key.

Chances are guys, it's the passengers door central locking solenoid that's either packed up or messing about.

These should be individual, one solenoid per door.

Then how come it works fine by key?

Martin

Martsford

Just so people don't get confused, The passenger front door locks when using the key but only locks that door, the other 3 doors remain lockable and unlockable off the remote,

Martsford

Where would I find the solenoid??

H3lsing

If you have washed the car recently water could have ingressed passed the driver's door window seal. If that happens it falls directly onto the micro switch in the driver's door and plays up with the remote central locking and normal door locking with the key.

There is an article on it here.

Thats totally different then and differs from what you say in your initial post, it's either the said solenoid then or a connection problem.

Martin

Martsford

I fully appreciate your comments Martin, but I never actually mentioned when locking the passenger door with the key will lock all 4 doors, If I worded the post wrong then I do apologise.

Martsford

Where is the door solenoid located Martin?

Martsford

Where is the door solenoid located Martin, I presume in the effected door somewhere?

martysmartie

Yes, you will need to remove the door card.

Martin

Martsford

Ok thank you, this may be a dumb question but what does the solenoid look like? Thanks all for your input I will have a look at the car tomorrow providing it's not snowing.

Martsford

Hi Guys, an update to the problem I'm having, today I've pulled the door card off the affected door, disconnected the latch from the power and tested it. There is power going to the door, once I'd reconnected everything back up and attempted to lock the car, it locked but then automatically unlocked itself and continued to do this until I manually locked the affected door, after locking that door I then attempted to lock the remaining key from the remote with success.

I'm now pretty confident it is the latch/solenoid itself that is causing the problem, could someone confirm that this is the problem or if there's something I'm missing.

Davemurphy007

The door solenoid is definitely your problem and you need to change it to get the central locking to work properly. They are a bit of a pig to change and a new solenoid was around Ł85 last time I biught one.

It's a REALLY common problem. I only know of one person who's had a problem with fuse 63 but the good old internet makes out that's the more common fault. I've had 4 mk1 Focus's in both 3 and 5 four guise and I've had to change a front door solenoid on every single one.

Martsford

Thank you for your advice Dave, is the solenoid part of the latch or can it be bought separately? Whilst I had the door card off I did notice getting the latch off is going to be a bitch.

Davemurphy007

You can't buy the solenoid separately the whole thing is a single piece of kit. You've already been to the part you need to replace because you did a voltage check on the plug. You'll need to disconnect all of the connecting rods from the keyhole, the external door handle and the internal door handle and then remove it.

You WILL cut your arms to shreds because the inner door skins are sharp and the solenoid is a pig to maneuver out.

dont know if it helps but every time i have had problems with focus locks it has always been the bloody drivers side not the affected/ problem door

Martsford

I've read many articles stating they are having problems with the drivers side door, but as I've said its my front n/s that's not doing as it should, I found it quite strange as up until a few days ago it was working fine, even first thing in the morning before it played up it was fine, then all of a sudden it started playing up. I've managed to get a few quotes for the newish part from 1stchoice auto parts, I know it's probably a 2nd hand part but I've unfortunately not got the kind of disposable income to start looking at buying a brand new parts.

Thanks everyone for your input and advice I will get the part ordered in the week and providing the weather is fine next weekend I will attempt to replace the part.
