Keys and Locks, Immobilizer System Keys and Locks 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. BUILT-IN KEYS KEY NUMBER TAG Immobilizer System The immobilizer system protects your vehicle from theft. If an improperly-coded key (or other device) is used, the engine will not start. When you turn the ignition switch to the ON (II) position, the immobilizer system indicator should come on briefly, then go out. If the indicator starts to blink, it means the system does not recognize the coding of the Honda smart key or built-in key. Turn the ignition switch to the LOCK (0) position, release the ignition switch and push it, or remove the built-in key, and reinsert it. Then turn the switch to the ON (II) position again. The built-in key (see page 181 ) fits all the locks on your vehicle. 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. Use only Acura-approved key blanks. Keep the keys away from liquids. If they get wet, dry them immediately with a soft cloth. The keys do not contain batteries. Do not try to take them apart. 150
