Diagnostic Service and Fee Deduction Policy

We value your trust in our services and strive to provide you with the best possible experience. When you’ve already paid for our diagnostic services and shipping, please be aware of the following policy regarding diagnostic fees and non-functional parts:

  1. Non-Readable or Previously Worked-On Parts:

    • If the parts you send to us are non-readable, damaged, or have been previously worked on by another party, making it impossible for us to perform the requested services, here’s what you can expect:

    a. Diagnostic Fee Deduction: We will deduct the diagnostic fee of $80 from your total payment. The remaining balance will be used to cover return shipping costs. Any remaining balance will be refunded to you, and the parts will be shipped back.

    b. Options for Further Action: We will provide you with an assessment of what additional parts or repairs are necessary to proceed with the programming successfully. You can then decide whether to proceed with these additional steps and associated costs.

Please Note:

  • We do not offer diagnostic advice. Our services involve reading and writing files, saving original and donor files, and enhancing the functionality of your device or system.
  • For all post-sales inquiries, including order status, tracking information, or technical issues such as a vehicle not starting or an airbag light indicator, please email us at [your email address].
