2001 Lexus ES 300 User Guide 1 - Page 395

IN CASE OF AN EMERGENCY IF YOU LOSE YOUR KEYS OR LOCK YOURSELF OUT You can purchase a new key at your Lexus dealer if you can give them the key number and master key, because your vehicle is equipped with the engine immobiliser system. Even if you lose only one key, contact your Lexus dealer to make a new key. However, if you lose all your master keys, the dealer cannot duplicate key but only replace the whole system. See the suggestion given in "Keys" on page 7. You can use the wireless remote control system with the new key. Contact your Lexus dealer for detailed information. If your keys are locked in the vehicle and you cannot get a duplicate, many Lexus dealers can still open the door for you, using their special tools. If you must break a window to get in, we suggest breaking the smallest side window because it is the least expensive to replace. Be extremely cautious to avoid cuts from the glass. 377
