A touch sensor assembly. The touch sensor assembly may include a housing, at least one touch sensor and a sensor cover. The sensor cover may identify a touch area associated with each touch sensor. The housing may form a water tight cavity for the sensor cover and the touch sensor when coupled to an housing cover. A raised dome may be provided, e.g. on the sensor cover or another element, to provided tactile feed back. LEDs may be provided for illuminating the touch areas and/or sensing ambient light. A controller may control the illumination level of the LEDs in response to sensed ambient light. Adjacent key suppression algorithms are also provided.

What is claimed is: 1. A method of monitoring a plurality of touch areas of a touch sensor assembly, said method comprising: identifying a first signal of a plurality of signals that exceeds a threshold level for a first time interval, each one of said plurality of signals corresponding to a different one of said plurality of touch areas, said first signal corresponding to a first touch area of said plurality of touch areas; providing a first output signal associated with said first signal; identifying a second signal of said plurality of signals that also exceeds said threshold level for said first time interval, said second signal corresponding to a second touch area of said plurality of touch areas; and changing said first output signal to a second output signal associated with a simultaneous touching of said first touch area and said second touch area if no other of said plurality of signals exceeds said threshold level for said first time interval. 2. A method according to claim 1, wherein said threshold level is a negative level relative to a reference voltage. 3. A method according to claim 1, wherein said first output signal is a binary coded decimal value corresponding to said first touch area. 4. A method according to claim 1, wherein said second output signal corresponds to a command for locking all doors of a vehicle to which said touch sensor assembly is coupled. 5. A method according to claim 1, wherein said second output signal corresponds to a command for enabling or disabling an auto lock of all doors of a vehicle to which said touch sensor assembly is coupled. 6. A method according to claim 1, wherein said time interval is about 250 milliseconds. 7. A method of monitoring a plurality of touch areas of a touch sensor assembly, said method comprising: identifying a first signal of a plurality of signals that exceeds a threshold level for a first time interval, each one of said plurality of signals corresponding to a different one of said plurality of touch areas, said first signal corresponding to a first touch area of said plurality of touch areas; providing a first output signal associated with said first signal; identifying a second signal of said plurality of signals that also exceeds said threshold level for said first time interval, said second signal corresponding to a second touch area of said plurality of touch areas; and changing said first output signal to a second output signal associated with a simultaneous touching of said first touch area and said second touch area if a reference signal corresponding to a reference electrode does not exceed said threshold level for said first time interval. 8. A method according to claim 7, wherein said threshold level is a negative level relative to a reference voltage. 9. A method according to claim 7, wherein said first output signal is a binary coded decimal value corresponding to said first touch area. 10. A method according to claim 7, wherein said second output signal corresponds to a command for locking all doors of a vehicle to which said touch sensor assembly is coupled. 11. A method according to claim 7, wherein said second output signal corresponds to a command for enabling or disabling an auto lock of all doors of a vehicle to which said touch sensor assembly is coupled. 12. A method according to claim 7, wherein said time interval is about 250 milliseconds. 13. A method according to claim 7, wherein said reference electrode is disposed between adjacent ones of said plurality of touch areas.
