MechanMagic Nissan Key Fob Replacement CWTWB1U808 3-Button (2010–2019) — Battery Included, Bench-Tested

MechanMagic replacement key fob CWTWB1U808 is a brand-new 3-button keyless remote designed to replace lost or damaged Nissan push-button start fobs for compatible 2010–2019 models.

This MechanMagic remote is a direct-fit aftermarket transmitter that matches the FCC ID CWTWB1U808 and part numbers 285E3-1KM0A / 285E3-1KM0D. It ships with battery and onboard electronics preinstalled and is fully bench-tested before leaving the warehouse. Please note: cutting the physical key and programming the transponder requires a locksmith or dealer—some dealers may decline to program aftermarket units, so a locksmith is often the fastest option.

Which Nissan models and years will this remote work with?

This fob is compatible with several Nissan models that used the CWTWB1U808 transmitter. Confirm vehicle compatibility using the fitment tool and your current remote’s FCC/part number to ensure a match.

• 2010–2014 Nissan Cube
• 2011–2017 Nissan Juke
• 2011–2015 Nissan Leaf
• 2011–2018 Nissan Quest
• 2019 Nissan Versa and 2014–2019 Versa Note

How do I program and prepare this replacement key fob?

The MechanMagic remote arrives ready to be cut and programmed but does not come pre-programmed to your vehicle. Programming requires dealer or locksmith equipment because the transponder chip (type 46) must be synced to your car’s immobilizer system.

• Transponder chip: 46 (requires professional programming)
• Included: battery and preinstalled electronics; sold as a 3-button transmitter
• Recommendation: use a locksmith if a dealer refuses aftermarket fob programming

What features and build quality can I expect from this aftermarket fob?

MechanMagic ships a new, unused keyless remote that has been function-tested with bench tools to verify electronics and button operation. The housing, buttons, and circuit are built to match OEM form and function, offering a cost-effective replacement solution.

• 100% new remote with pre-tested electronics
• 3-button layout for lock, unlock, and trunk or panic as applicable
• Battery included so the unit powers up on arrival

Are there any important installation notes or limitations?

This transmitter is intended for Nissan vehicles that use a push-button start and the specified FCC ID/part numbers. Verify button placement and appearance with your existing fob photos to avoid mismatches. The product does not include key cutting or programming services.

• Only compatible with push-button start Nissan models listed above
• Confirm FCC ID: CWTWB1U808 or part numbers before purchase
• Sold as remote only; locksmith or dealer required for cutting/programming

Who is this for: MechanMagic’s CWTWB1U808 remote suits Nissan owners who need a reliable, brand-new replacement fob without paying OEM prices. It’s ideal for those who can arrange professional key cutting and programming through a locksmith or dealership and who want a pretested unit that restores full remote functionality to compatible 2010–2019 Nissan push-start vehicles.
