Keys and Locks The valet key works only in the ignition and the door locks. You can keep the trunk, trunk release handle, trunk pass-through cover, rear seat trunk access, and glove box locked when you leave your car and the valet key at a parking facility. You should have received a key number tag with your keys. You will need this key number if you ever have to get a lost key replaced. Keep the tag stored in a safe place. If you need to replace a key, use only Honda-approved key blanks. These keys contain electronic circuits that are activated by the Immobilizer System. They will not work to start the engine if the circuits are damaged. Protect the keys from direct sunlight, high temperature, and high humidity. Do not drop the keys or set heavy objects on them. Keep the keys away from liquids. If they get wet, dry them immediately with a soft cloth. The DX model keys do not contain batteries. Do not try to take them apart.
