How do I prepare and program these replacement key fobs?

Each LYFUCESS unit arrives with the transponder chip and a battery already installed, but the metal key blade is uncut and the remote will need programming to communicate with your vehicle. Blade cutting requires a professional locksmith or dealer, and programming depends on your vehicle’s support for self-programming; some vehicles require dealer or locksmith programming.

• Have the key blade cut by a locksmith or dealer
• Follow included programming steps if your vehicle supports self-programming
• If self-programming isn’t supported, schedule programming with a dealer or locksmith
• LYFUCESS tests each unit prior to shipping for basic function

What should I expect in build, function, and warranty?

These aftermarket LYFUCESS fobs are built from durable materials and include an installed chip and battery for immediate use after cutting and programming. They replicate factory button layout to work with your car’s keyless entry features but do not carry OEM branding. A 90-day after-sales option covers replacement or refund for qualifying issues.

• Includes transponder chip and battery pre-installed
• Aftermarket design—no GM logos or OEM branding
• Constructed to match original button layout and function
• 90-day customer support for refunds or replacements
