Keyless Access System Keyless Remote Low Battery If the remote battery becomes weak and the power door lock/unlock operation is disabled, you should insert the remote into the keyless access remote slot to set the power mode and start the engine. After inserting the remote into the slot, operate the engine start/stop button as previously described (see pages 184 and 187 ). For more information on the keyless access slot, see page 197 . Inserting the remote does not charge the remote battery. You should replace the battery as soon as possible. Instruments and Controls The battery in the remote normally lasts about 2 years. To ensure maximum battery life, do not store the remote close to electrical devices such as computers or TVs. When the multi-information display shows ''CHANGE KEYLESS REMOTE BATTERY,'' replace the battery as soon as possible (see page 181 ). 194 2013 TL
