How to remove old BMW key fob emblem:
If your key fob emblem isn't already missing, the removal process is incredibly simple. Just pick at the edges with your finger nail until it peels off. The emblem is only held on with a sticker like adhesive. It is not permanently fastened down.
Once the emblem is removed you want to make sure the surface is perfectly clean. We recommend using Goo-Gone to get the bulk sticky residue off and then go back with some rubbing alcohol to ensure no grease is left behind. Use a lightly wet cotton swab. MAKE SURE TO SPRAY THE WET THE COTTON SWAB LIGHTLY. Do not spray the key fob directly with Goo-Gone or rubbing alcohol. Hold the cotton swab aware from the key fob while applying the degreaser, this will ensure no liquid gets inside and ruins the electrical components. Having a nice clean surface will ensure the new emblem sticks on properly and will last a long time.
How to apply the new BMW key fob emblem:
Now that you have a perfectly clean surface, peal off the new emblem from the paper backing. Make sure not to touch the sticky side with your fingers. The oil from your fingers will transfer to the backing and it will prevent a proper application.
A good technique is to take an exacto knife and apply the emblem to the end and then slowly lower it down on the key fob making sure it is centered. Press down firmly and hold for a few seconds to make sure the new emblem is getting good contact.
