Honeywell released a new wireless key fob that allows homeowners to summon police, fire and other designated emergency contacts with the push of a button. The 5834-4 Wireless Key offers up to eight programmable functions, including the standard lock and unlock functions, and is 15 percent smaller than previous key fob models. The 5834-4 also features an estimated battery life of up to five years and real-time LED to confirm transmission status. Recessed, tactile keys and push-button operation may help reduce false alarms. The key is compatible with Honeywell’s 5800 series of wireless products.
