BMW E30 Key to Remote Keyfob DIY Conversion
Posted: Fri Mar 25, 2011 9:20 pm
Hi. This is my latest DIY, couldn't find a better sub-forum to post
Anyway, we will be going from this

To this (Remote Kit install will follow some time soon):

For 10 Euro, I got 2 duplicates of the original key. Make sure you get the duplicates with the all-metal version, not the plastic handle.

Blank blade removed for measuring:


Using an angle grinder, I cut both keys:


Newly cut key below blanks from keyfob, showing what needs to be removed in order to fit within the remote key enclosure:

Using my dremel, I started to grind just a bit each time, testing fitment.


Had to skim them about 0.5mm, don't worry though, the key won't bend!

The glue I chose to use, is super strong. Once it settles, the key will not be able to be removed from the key carrier. I had a spare keyfob for testing, and I just threw it away, they key would not get out.

Applying glue, aligning blades and letting it harden:


Excess glue is removed and blade is re-assembled to the keyfob

Now, the E30 is too wide so I was going to trim it but I don't know if it acts as a stop when the key goes into the lock, so I chose to grind the plastic housing a bit.
