Then validate the technician's certifications, liability protection, and security checks. Inquire about what specialist tools they use (such as Xhorse, Autel IM608, Advanced Diagnostics Smart Pro) and if they clone by chip.
Validate website response times and on-site capabilities, along with cost methodology (comprehensive fees vs. itemized charges for travel, labor, and key blank). Look through client reviews to gauge consistency with punctuality, service outcomes, and aftercare support. Ensure they can provide original manufacturer keys, handle remote programming, and handle situations with no existing keys without needing ECU replacement. Obtain a formal quote, vehicle identification protocol, and warranty coverage terms.
