Thread: Stupid Key Question - Can you get ignition keys to match door keys?

G'day Alistair, have you a photo of the differences of the std SIII door lock and the anti-burst SIII door lock because I'm not sure which one I have?

Thanks
Nathan.

Hello from Sherwood.

The two types are quite different and easy to identify - they are shown in the parts manual.

The older lock has a sliding latch that slips into a two stage retainer/striker on the door frame - looks a bit like the normal Lockwood door lock.

The anti-burst locks have a rotating latch that catches a cylindrical retainer on the striker plate.

This striker is for the anti-burst locks:



These are the anti-burst handles:



The second photo was taken while I was swapping barrels between locks.

The truck is a 1975 Series 3 - by that stage the anti-burst locks would have been standard fitment.

Cheers,

Neil

Hi Nathan

Neil seems to have got there first with a photo of the anti burst lock.

Attached are the extracts from the parts maunal and the optional equipment manual.

Not quite sure about the cut off date from one type to the others. Mine was a 1982 vehicle and it was definately fitted with the older syle locks when I bought it. Anyway, one way or the other, something to check.

Hello again.

I suspect the ambiguity has its roots in origins.

My truck was built in Australia in 1975 and subject to the Aust Design Rules which probably mandated anti-burst door locks among a few other safety bits. I seem to recall that your truck came as an import from the home country.

Over to the rivet counters - here's your chance.

Cheers,

Neil

Thanks Neil and Alistair, I have a 1977 CKD and it has the older type like the SIIa.

Thanks again that's something I'll have to put on the upgrade list. by the way what's the benefit of the anti-burt locks?

Thanks
Nathan.

Basically if you flip your car over or have a real prang which bends the body and distorts the doors and or door frame the anti burst locks will... prevent the doors from bursting open leading to bits of the occupants comming out of the in motion vehicle and getting damaged. (Not that it makes so much difference in a soft top but...).

The rotating horseshoe shaped hasp on the locking mechanism strikes the striker on the door frame as the door closes and rotates shut into position preventing the door from popping open if the door frame is distorted. Also the mechanism is wedge shaped with a receiver on the door frame which prevents the door from distorting upwards and holds it closed much more positively and with less rattles. This also tends to improve the efficiency of your door seals if they are in half decent condition.

On the older locks which look like a normal door lock, the door is held shut, but if the door or frame distorts, the door will pop open. It also tends to rattle a lot (if you can hear it over the appaling din of the gearbox!).

As pointed out, the second edition ADRs probably mandated anti-burst as standard earlier than what they became standard in the UK which explains why your earlier truck doesn't have them.

As an additional benefit it makes the land rover doors a lot harder to crowbar open - it doesn't take that much effort to distort a series door with standard locks by enough to make it pop. The anti burst locks also prevent this.

That is a lovely smooth white concrete floor you have there Neil.

Are you sure that you actually have a SIII.... I can't see any oil stains anywhere!

If you don't already have them. All available via google, but saves the effort. Other bits in there as well - self explanatory if you look.
