diamond key and the Tamper Dot

Hi, I was thinking on changing my old key to the new diamond shape
one ,but on reading through some previous post about the Tamper dot
they say that your key's memory has the car's vin number and mileage
stored in it's memory. our cars store our mileage/vin number information in 3 places, the ecu, the key, and the cluster..if one of these do not match up it will trigger a tamper dot showing that the mileage has been tampered with.

Has anyone changed their old key to the Diamond shape one, and has the tamper Dot appeared after changing their key's inside's of over.

Changed my keys from the 'Square' type to the diamond type. No tamper dots. Look up luckysnafu's DIY on diamond keys and you shouldn't have any issues. I followed his diy and have two working diamond key remotes. Very easy to follow. Hope this helps!

Hi, I did this to a diamond key, programmed it into my 1999 323i car as it has the old square type key, to check that it was opening/closing the doors which it was ,I then split the diamond key open took out the 8 pin IC thinking it was the keys transponder and also left in the rechargeable battery and the coil warpped part on the circuit board to recharge it, I then put my old keys transponder into the diamond key, and went to try it on the car. the remote did not open the doors ,opening the drivers door with key set off the alarm , put the key into he ignition and the key would not start the car. which means the 8 pin IC can't be a transponder.
I then used my old square remote to open the drivers door and which also turned off the alarm and tryed the diamond key again and the car still would not start

Here...try this link. This is the link I used when I converted my 323i "Square" type key to my "Diamond" style keys. I still no Tamper Dots...
