Dashcam hardwired by Halfords = no remote locking!

Mark Five

Recommended Posts

Hi everyone - I had a new dashcam hardwired by Halfords on Saturday, and when I got to my (distant) destination afterwards found that the remote locking wasn't working (but it locks ok with the key, and all other electrics work fine).

I've tried the spare fob and that doesn't work either, so it's not the fob batteries. I took a look at the cockpit fusebox and they'd piggybacked it into F5, which doesn't mention anything to do with remote locking in the handbook.

I'm taking it back to Halfords tomorrow, but after reading a few posts on here about remote locking problems I'm not confident they'll diagnose or fix it.

Has anyone got any ideas or experience of this? I'm convinced the fault occurred at installation, so I hope it doesn't lead to a David & Goliath battle..

Any help would be greatly appreciated!

if they disconnected the battery, or pulled fuses for door module

you may need to pair the remotes again, not sure how it done, but if you google it, you should be able to find it

but I would take it back first, to see if they can sort it

UPDATE: went back to Halfords who checked over the wiring and connections, disconnected the dashcam wiring to see if that cured the problem (it didn't), and reconnected it all again. They put a new battery in the key and that didn't cure anything either (I said it need pairing again, they said it didn't). I tried pairing it today but all was silent (no chime) - so I'm still without remote locking.

Halfords said to get it diagnosed and repaired by an independent/dealer, and they would cover the cost IF it could be proven it was their fault. So now I'm off to get a diagnosis..

Thanks Steve - have just tried that method (and a couple of others) but to no avail - I'm just not hearing the chime with any of them.. it seems like the signal is just not getting through, or if it is, whatever activates the remote locking is knackered. Everything works fine otherwise, including locking the doors with the keys.

I see there's mention of a door module battery in the fuses section of the handbook - I wonder if that's relevant?

I'll take the car round to my local indie to get him to attach his magic box and see if he can diagnose what's going on, because I'm stumped!

Thanks guys.. I tried all of the methods listed below so when I get some time I'll visit the indie.. 


I just can't understand why it should have failed in the first place - would mistakenly removing (then replacing) a particular fuse cause a code reset? If that happened when they were piggy-backing the dashcam wiring into the fusebox then i could understand that, and hopefully it would be an easy fix with the proper software.

It appears that when the dash-cam was hard-wired the key memory was wiped, probably through the wrong fuse being pulled (and re-inserted when they realised the mistake) - the same effect as having a flat car battery.

On another note, and as R2e correctly said, all the methods described here http://www.bluejag.co.uk/S-Type-keyfob-reprogramming.php didn't work on my particular vehicle - it had to be done via the indie's SDD/IDS system.

Lesson learnt: don't let Halfords fiddle with your fusebox unless they know EXACTLY which fuse to pull.
