Acura 2007 MDX - Owner's Manual - Manual (Page 131)

Always use the fully-extended key
when you insert it to the ignition
switch. If the key does not fully
extend, the immobilizer system may
not operate properly and prevents
from starting the engine. The key may come in contact with
your finger while being retracted or
extended. Make sure your fingers do
not touch the pivot of the key when
retracting or extending the key.
The master key can be retracted into
the remote transmitter. To use the
key, push the release button to
release the key from the transmitter.
The key should be fully extended.
To retract the key, push the release
button and at the same time push the
key into the remote transmitter until
it is securely latched.
