- Are your key's OEM or Aftermarket?
- The roundel is brand new and a Genuine BMW part. Keep in mind that these naturally yellow over time.
- Both the housing and PCB Board are Aftermarket. We work closely with our manufacturer to refine various aspects of the key and are currently on the 3rd revision. We also re-spun the PCB to address the slow current draw issue causing batteries to die prematurely, available only through Gates Innovations.
- Are the buttons metal or plastic?
- Both the silver and black buttons are plastic. The black buttons just have a textured finish versus smooth on the silver buttons.
- How much does the new key weigh?
- The modified F85 X5M key weighs: ~75g
- The OEM EXX key weighs: ~35g
- Will you send my donor key back and will it still work?
- Yes, we'll send your donor key back. This is a 1 to 1 modification, thus your donor key will no longer function after the modification has been completed. We suggest that you hold onto your donor key parts in case you ever want to revert back.
- Do you offer a warranty?
- Yes, this service includes a non-transferrable Limited Lifetime Warranty. Please reach out to email@example.com to submit a warranty request.

- Will everything still work like before?
- Button functionality, comfort access, vehicle feature coding, and dealer key scanning will continue to work as expected.
- Do I need to program/code the new key to my car?
- No, the new modified X5M key will function right out of the box.
- I only have one key, what are my options?
- We offer an expedite option where you jump to the front of the line, receive a guaranteed 1 day turnaround time, and return overnight shipping via UPS (within the Continental US only). International customers receive 2-3 day return shipping via UPS Worldwide Expedite. Please understand that there may be shipping delays outside of our control.
- Purchase a new key fob remote through your local BMW dealer prior to sending your key in for the modification service. You can purchase the key fob remote portion without the physical key. Your original physical key can be used with your new key from BMW as your new X5M key will have a cut key.
- Is this safe? What happens if you break my key? How do you know my key works before you send it back?
- Because there is a human element in the modification process, a risk is going to exist. However, we've completed hundreds of keys without a single catastrophic loss. If we were to damage your key beyond repair during the modification, we would reach out immediately and cover costs associated with purchasing a new key through your local BMW dealer and also refund your modification service purchase.
- We test your key for functionality prior to performing the modification service. We use a software defined radio to read out each button press, which we capture in HEX format, to confirm initial functionality. Upon completion of the modification, we confirm each button press matches the original captured HEX strings during the initial functionality test.
