Hi,

I am a locksmith that specializes in automotive, particularly the Euro stuff nobody else likes to mess with. Several months ago I spotted a Grenadier heading down I40 and it caught my eye, and have been fascinated with them ever since. I do a lot of work for the local Rover dealer and its customers, and absolutely understand the motivation behind building something with old Rover looks and capability but without the pitfalls of the current Rover reliability.

Anyway, there is absolutely no data available for how key programming is accomplished or what immobilizer system they use. There have been several questions raised in locksmith forums about the Grenadier, and believe it or not, a thread here has the most information I've found to date. Local Dodge dealer had one on their lot for sale, but it didn't last long and was gone literally hours before I could get down there to investigate.

If there is a Grenadier owner within an hour or two of Knoxville, would you be willing to let me take some measurements of your key in order to try and determine which DSD (depth and spacing dimension) it uses, or create one if it's truly unique to Ineos? This will involve measuring the key blade itself with a micrometer and running out some test keys. Most likely the volunteer will wind up with a spare key or two, although it will only be useful for unlocking the door, not starting the vehicle.

Furthermore I'd like to poke around a bit and at a minimum, plug in to the diagnostic port and see if I can identify any of the immobilizer components electronically, and if not, possibly (depending on how amicable the owner is) remove a few interior panels to try and determine the location and manufacturer of immo components.

I know the BMW driveline would suggest BMW immo components, but BMW has not used a keyed ignition since the late 2010's, and it did not use the chip type identified in another Grenadier key (4A).

Total time I'd need with the vehicle is about 2 hours. I can come to you at your home or work, and make the promise no testing will be done that would render the vehicle immobile.

If anyone nearby is interested, let me know either by PM or email, ben@lockmedic.com. Include the city you live in, and your preferred method of contact.

Thanks!

WHat blade was cut (for your truck)?
How did you program it?
 
everyone here has a few spare keys, from the door lock recall.
The dealer made me turn mine in. Are the keys even the same (the metal part)? I thought the locks themselves have different barrels. Maybe not.

No I didn't get to that. I bought a BMW blank from AliExpress and I have to get to a locksmith or a kiosk.
