2nd fob

[tomfromtulsa]

I have one fob that works and want to purchase a 2nd fob. Can I buy a used one from fleabay/salvage or should I buy a new one? Can I program a new or used one or should I take it to a mobile locksmith for programming? The locksmith wants $350 to program a new fob and cut the key.

Car is a 2015 BMW X1 (E84) with comfort access.

Locksmith normally have everything needed and often quote price with fob supplied.
Any reasons to have a blade cut?

It's a safer bet to buy a new one, and doesn't make a difference for the process. Copies can be had on Amazon/eBay for under $30.

Getting the metal cut would ensure that you are able to enter your car if somehow the security system rejected your aftermarket key.

I am going to try to program a backup through this method, will update on how it works.

This will not work for E84. Duplicating keys is more involved, and requires scanners in a region of $1000.
