Remote Keyless Entry System - Volvo 2003 C70 Operation And Care Manual

One turn with the key towards lock in the drivers door locks both doors and the trunk.
Use the switch on the front door armrests to lock/unlock the car from the inside.
Check the action of the button on the other door to verify its function (lock/ unlock).
WARNING!
If the doors are locked while driving, this may hinder rapid access to the occupants of the car in the event of an
accident. (Also see information on "Child safety locks").
NOTE:
If a door is not closed completely, the courtesy lights will stay on and a chime will sound until the door is closed.
As an added anti-theft measure, new keys have been developed which may take slightly longer to copy or replace if
the original keys are misplaced. Duplicate keys may be ordered from your Volvo retailer.
Immobilizer (start inhibitor)
Each of the keys supplied with your car contains a coded transmitter and receiver (transponder). The code in the key is
transmitted to an antenna in the ignition switch where it is compared to the code stored in the start inhibitor module.
The car can only be started if a properly coded key is used.
If you misplace a key, take the other keys to an authorized Volvo retailer. The existing code in the start inhibitor
module and all the keys will be erased as an antitheft measure and a new code will be programmed in.
NOTE: Not more than one of the keys for your car should be kept on the same key ring. This could cause conflicting
signals to be transmitted to the ignition switch, making it impossible to start the car.
This device complies with part 15 of the FCC rules. Operation is subject to the following condition: (1) This device
may not cause harmful interference, and (2) this device must accept any interference received, including interference
that may cause undesired operation.
The key number codes are stamped on a separate tag supplied with the keys. This tag should be separated from the key
ring and kept in a safe place.
