Duplicate Smaller Key?

[ANNML]

On most of my previous cars, I’d have a regular non-fob type duplicate key made so that if I was going hiking or whatever, I could leave the fob in the car and just tuck the small key in my sock.

I’d like to do the same thing with my Grenadier but I don’t know if this screws with the programming like it does on some other cars. For example, the older Rover LR3s and some other LRs have some sort of lockdown mechanism where if you leave a fob inside the vehicle and then lock the car with a non-fob key, it can cause the vehicle to enter a locked mode (don’t know a technical term) and then it’s a real problem getting access again and can only be done at a dealer who has a fob programming thingy — and you’d have to tow it to a dealer. Several locksmiths told me this when I was trying to have a key cut for one of my Rovers.

Anyone familiar with this or know if it can be done with the Grenadier without causing problems?

I wouldn't risk it on the Grenadier. It uses a similar security system to modern Rovers. Leaving a fob inside while locking with the physical key can trigger the anti-theft immobilizer, just like you described. You'd likely lock yourself out and need a dealer to reset it. Your best bet is to just take the whole fob with you or use a faraday pouch to block its signal if you're worried.
