Hey Kev - that makes the idea of having a fresh spare keyfob battery in the glovebox really important before heading to the outback!

can you still get in the car if the battery is flat?

just thinking about keeping the spare inside the car---;)

Yeah mate, perfect sense. I was fiddling with the fob today and figured that it had to be something to do with splitting the other side of the case.....but was a bit reluctant to apply too much force.

I'll give it a crack....I'm now guessing the batteries are COTS....get them anywhere?

Cheers mate.

Yup sure does.

Trap for young players....like myself. I was thinking how much a screw-up it would be to be in the middle of nowhere and get a flat battery.

I assumed you'd get a week or so warning....I assumed wrong.

Cheers,

Kev.

Yeah mate, you can. The 'blade' that Stig0000 is talking about, is a manual key.

Cheers,

Kev.

and to start with a dead key,, under the steering colem on the right top side youl feel 3/4 lines,, put the key there with buttons down and BAM she starts,,

Yeah, but Nick would the alarm be screaming till you got the battery in.
and would the alarm stop if you used that spot under the steering wheel ?


Cheers Ken

it gose off, and once the car starts it stops,, iv tryed it with no battery at all in the key,

What the.....no battery in the key fob?.....it must still have been holding some charge, otherwise what would be the point of the security system. How would the car 'know' that there is a fob there...the right fob for that car?

I imagine there is something still held within the fob, like mobile phones and PCs show accurate time when switched on, even after the battery/power has been removed.....the reason you can change the battery and not have to re-code the car.

That's my punt anyway....LOL!!!!

Re the "real" key set up for the D4, as it still looks like a D3 key but with an old style replaceable battery, I wonder if one can order a D4 key from Land Rover and have them code it for a D3?

If so, this would solve the problem of the rechargeable battery circuit failing by eliminating the requirement for a rechargeable battery. It just seems to me that if we can un complicate some of the D3 systems, maybe a guy could get at least 15 years out of the vehicle.

These vehicles are getting too much like a cell phone - when it quits, you throw it away.
