What to know

Same 6-year life as the KeyFit 30, with the expiration printed on the underside labels. FAA certified for aircraft use without the base.

The date of manufacture is on the seat itself. The expiration date is printed on an adhesive manufacturer label on the underside of the car seat and, for infant seats, on the bottom of the carrier and on the base. The same label carries the date of manufacture and model number.

Safety note: SeatCheck summarizes manufacturer and NHTSA guidance, but the label on your own seat and its manual are the final word. When in doubt, contact the manufacturer with your model and serial number.

Frequently asked questions

How long is the Chicco KeyFit 35 good for?
The Chicco KeyFit 35 has a useful life of 6 years from its date of manufacture. The exact date is printed on the seat's own label, so check the sticker on the shell or base rather than counting from the purchase date.
Where is the expiration date on the Chicco KeyFit 35?
The expiration date is printed on an adhesive manufacturer label on the underside of the car seat and, for infant seats, on the bottom of the carrier and on the base. The same label carries the date of manufacture and model number.
Should I replace the KeyFit 35 after a crash?
Chicco recommends never using a car seat that has been involved in any crash, including a minor one. This is stricter than the NHTSA guideline, which permits reuse after a qualifying minor crash. Chicco's position is that a collision can cause unseen damage that compromises the seat's ability to protect your child in a second crash.
