Four colorful and textured keys. Drivers key has a push-button light and 3 fun sounds designed to go easy on grown-up ears. 3 AG13 (LR44) batteries included. Babies love the jingle sound keys make, the feeling of them tumbling in their fingers, or nibbling on the fob. And FunKeys are a safe way to let them play! Not only are there three sturdy keys, but the fob plays four car sounds (horn, engine, alarm, doorbell) and comes with a flashlight! They may be even better than your keys, and they'll keep baby busy for hours. Comes with 2 AAA batteries.
