❓ Frequently Asked Questions (FAQ)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Q1: Does this key include the BMW logo?
A: No, this is a high-quality aftermarket key and does not feature any official car brand logos.
Q2: What is a 4-track key?
A: 4-track keys have cuts on all four sides of the blade (high security), requiring a specialized laser-cutting machine. The HU58 is a 4-track profile.
Q3: Can a hardware store cut this key?
A: No, standard hardware store machines cannot cut 4-track laser keys. We recommend visiting a specialized automotive locksmith.
Q4: Is the transponder chip already inside the key head?

Q5: Will this work for my 2004 BMW?

A: We offer a 1-year free return policy. If the key is found to be defective by a professional, contact us for a full refund or replacement.
