Acura 2010 TSX - Manual (Page 122)

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.
The master key fits all the locks on
your vehicle. The valet key works
only in the ignition and the driver’s
door lock. You can keep the glove
box locked when you leave your
vehicle and the valet key at a parking
facility.
The valet key does not contain a
battery. Do not try to take it apart.
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.
Keep the keys away from liquids.
If they get wet, dry them
immediately with a soft cloth.
