The keys hold info in them (in the chip) here's some of it that I know for sure about
- The chassis #
- The present mileage, updated every-time you turn the ignition on / start the MINI.
- The key # ie, which issue #1, #2, #3 etc...
- The chip # used too start the MINI, this is encrypted, hence key shops cant read the key chip No (although this changes all the time technology etc...).
- 1st Gen pre face-lift the key a remote circuits where separate although in the same key, 1st Gen face-lift is all on the same circuit so it could hold the remote data as-well.
- Year & date of MINI
Some info can be read at the desk as they have key-readers fitted too the desk at reception, the mileage isn't always what's on the speedo as the speedo can easily be changed fooling a prospective buyer etc... etc... but not fooling anyone with the right equipment (again changing all the time).
Also I think the key will show up limited data when read from the desk but the rest can be accessed with better equipment
To give advice on the engine # as you look at the engine from the front of the MINI facing rear-wards the engine # is on the rear of the eng block at the rear left facing the bulk-head where the engine mount bolts too the block (if you look near the oil filter housing you're in the right area) not normally visible after a couple of years without cleaning, however it is also located on a white sticker in a similar place on the rear right of the rocker cover however this # is almost identical but it usually has a # or a letter different (I'm not sure why) than what is on the actual engine block, this is easily noticeable as it's on a large white sticker with a bar-code on-it
There's two #'s on the sticker it's the long one starting with W10B 16 (engine code), then mine has a combination of 8 # & letters, it's that last combination of letters & #'s that's the engine # on my actual log-book
. as I said 1 # or letter is usually different on the previous #'s to what is actually stamped on the engine block, I know the W10B 16 is the engine code & different on S
s (W11B 16), providing the rocker cover hasn't been changed this info should be correct
On the tag sticker with my ID on it under the bonnet the engine code is actually W10B 16A, the A may account for the extra letter / # that I've been going on about
This advice is for 1st Gen 1.6 petrol engines only
