Chicco KeyFit30 Review

I run a busy car seat inspection station and expectant parents are some of my most frequent clients. That means I see a whole lot of infant seats. I always breathe a sigh of relief when I’m scheduling an appointment and a parent tells me their seat is a Chicco KeyFit; because it’s just so easy.

Why do I love it? Let me count the ways!


Installation with the Base

Chicco KeyFit Lower Anchor Release

Chicco KeyFit Lower Anchor Release

Installing the KeyFit using the lower anchors is pretty simple.  The premium lower anchor connectors use a push button to engage/release.  They tighten with the pull of a single strap of webbing.

Chicco Keyfit Seatbelt Installation

Installing the KeyFit using the seat belt is also a simple proposition in most vehicles, thanks to the seat belt lockoff that’s built into the KeyFit’s base.  Simply pull the seat belt tight across the lap portion of the base, then slide the shoulder belt into the orange clamp to secure the base in place.

Recline Angle

The recline foot on the KeyFit’s base has a wide range of adjustment.  This means it’s easy to achieve the proper recline in any car without having to use a noodle.  This is a good thing because Chicco does not allow for a pool noodle to adjust the angle with this seat.

A bubble level indicator lets you know the recline is in the correct zone for your baby.

Installation Without the Base

Although the base is a cinch to move between vehicles, the KeyFit can also be installed without the base – very convenient when traveling or taking a ride with Grandma or a friend.


Infant Insert


Chicco KeyFit insert needs removed at 11 lbs.

The seat includes a substantial newborn insert that can help the smallest babies achieve a proper fit.  This insert must be removed when baby weighs 11 lbs, but the head rest can stay in until the child’s shoulders are using on the top harness position.

Handle Position

The carry handle is allowed in any locked position in the vehicle – space-saving and convenient! In fact, the KeyFit is one of the shortest infant seats in terms of front to back space.

Fit to Child

The 4 lb minimum weight and 7″ bottom harness position make this seat an excellent fit for preemies on up through average size newborns.

Older Babies

The max weight of 30 lbs, max length of 30″, or the child’s head being 1″ from the top of the 21″ shell means that most babies will not outgrow the KeyFit before they can sit up on her own the way some shorter-lived rear facing only seats sometimes do.

 Important Information: Where to Find

Chicco KeyFit FAA Approval Sticker

Chicco KeyFit FAA Approval Sticker

FAA Approval: the airline approval language is the red text on the large sticker on the left side of the base.  Note: like most rear facing only seats, the KeyFit is only approved for airline travel in baseless mode.
Chicco KeyFit Manual Storage

Chicco KeyFit Manual Storage

Manual Storage: The manual stores in the handy compartment at the front of the base.
Chicco KeyFit Expiration Sticker

Chicco KeyFit Expiration Sticker

Expiration: A 6 year expiration means that the KeyFit can be passed down through several Littles.  The expiration date and date of manufacture are printed on a sticker on the top of the base.  Another identical sticker is on the bottom of the seat itself — note that sometimes, the base and the seat itself will have different manufacture dates.


  • Front adjust harness
  • Fits preemies well
  • Push button lower anchor connectors
  • Seat belt lockoffs
  • Allows handle in any locked position


  • Seat is a bit heavy

Overall Thoughts

Is there anything I don’t love? The canopy is on the short side, and the harness straps like to try to fold/twist at the hips sometimes. Other than that, the KeyFit is easy to use, easy to install, a sure fit for tiny newborns on up through infancy.

Chicco did not provide this KeyFit for review and gave no compensation for the review. As always, the words are always my own.
