Emergency Key Blade Set of 10 for 2007-2012 Nissan Altima 2008-2010 Infiniti G37
Set of ten aftermarket uncut emergency insert keys for matching Nissan and Infiniti proximity-key housings. These are mechanical blades only, not electronic remotes.
Fitment and compatibility
- For matching 2007–2012 Nissan Altima and 2008–2010 Infiniti G37 smart-key housings that use the photographed short insert blade and black rectangular head.
- Approximate blade length: 4.4 cm. Compare the groove profile, shoulder, retaining features and head size with your original insert.
- Remote-housing identification references include CWTWBU735, CWTWBU624, KR55WK49622, CWTWBU619, KR55WK48903, CWTWBU618 and KBRTN001. These identify remote families, not a universal blade interchange.
- Year and model alone do not establish compatibility. A locksmith must verify the physical blade profile and fit in the original fob.
- No transponder chip is included. Not suitable where the insert itself requires a transponder to start the vehicle.
Included and installation
- Ten uncut mechanical insert keys with black heads and metal loops.
- No remote housings, electronics, batteries or immobilizer chips.
- Professional cutting is required. The mechanical blades do not require electronic programming; they do not replace or program the vehicle’s smart-key electronics.
Aftermarket replacement blades, not Nissan or Infiniti OEM keys. Detail photos show one blade from the ten-piece set.
