• Included: one keyless-entry remote with pre-installed circuit board and battery
• All units are pre-tested for button response and signal output
• No extra internal parts or batteries are required for programming

Will this fob look and feel like the original?

The SUPALAND shell and button layout mirror the OEM styling so you get the same ergonomics and button placement as your factory remote. While it’s an aftermarket product, the fit and tactile response are designed to match original fobs closely when installed and programmed.

• Matching button arrangement for lock, unlock, trunk, and panic
• Durable housing designed for everyday use and pocket carry
• Pre-fitted electronics preserve the original remote’s function once programmed
