HONDA 2010 Element - Manual (Page 82)

You should have received a key
number tag with your set of keys.
You will need this key number if you
ever have to get a key replaced. Use
only Honda-approved key blanks. 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.
The keys do not contain batteries.
Do not try to take them apart.
See page 77 for an explanation of the
remote transmitter's operation.
Immobilizer System
The immobilizer system protects
your vehicle from theft. If an
improperly coded key (or other
device) is used, the engine's fuel
system is disabled.
When you turn the ignition switch to
the ON (II) position, the immobilizer
system indicator should come on for
a few seconds, then go off. If the
indicator starts to blink, it means the
system does not recognize the
coding of the key. Turn the ignition
switch to the LOCK (0) position,
remove the key, reinsert it, and turn
the ignition switch to the ON (II)
position again.
The system may not recognize your
key's coding if another immobilizer
key or other metal object (i.e. key
chain) is near the ignition switch
when you insert the key.
