The Keyed Alike lock system allows a manufacturer or dealer to standardize each RV so just one key works with every door lock. In some cases, one RV could require up to seven different keys. Changing out all those locks could cost hundreds of dollars. Instead the efficient and secure Keyed Alike lock system offers consumers just one set of keys for all the locks on the rig. The Keyed Alike system is available on our complete line of RV entry, ramp and baggage doors. Not for sale in the aftermarket. Direct to OEM sales only.
