Yes I was initially told cannot change them. However on inspection you can.
Original outer should fit. For what they cost may aswell bang a new set on tho if yours are old.
Just use a decent brand. So they last.
Don't know how I've ended up reading this so far down the line. But for what it's worth for people in the future. Honda still provide new fobs and keys for certain setups .
I have brand new keyset and fobs for mine.
Haha same really. Yeah it's an 2007 Alphard. Quite a nice vehicle tbh.
Was looking for a Honda Elysion ideally but couldn't find the right one. So started looking at these, And quite liking Toyota atm.
