2017 BMW 5 Series Smart key Replacement - Fast, Affordable & Professional

Here's exactly what happens when I replace a 2017 BMW 5 Series key. I verify your identity and vehicle ownership. Then I decode the lock and laser-cut the blade. From there I connect my IM608 to the OBD port and read the BDC module's security data, calculate the encryption key, and register the new fob through the security sequence. After that, I test. Not just "does it start." I test every button, the remote range from 30 feet, the lock and unlock, the trunk, and three consecutive starts. On models with Comfort Access, I check both door handle sensors too.

A customer at the fundraiser dinner in Montecito watched me work on her 5 Series and said the testing was what stood out. She expected a quick handoff. Instead I walked across the parking lot pressing every button, tested the range, started the car three times, and checked the Comfort Access sensors on both door handles.

Her smart key, FCC ID NBGIDGNG1, was a 4-button smart key. Every function verified and three clean starts confirmed before I packed up. I told her that testing is the part most locksmiths skip, and it's the part that catches problems before they strand you somewhere.

That testing is included in the 361 I charge. Dealers charge 651 and some hand you the fob and close the ticket without thorough testing.
