<h3><strong>Be sure to review all programming steps before proceeding</strong></h3> <h3>2010 ODYSSEY - - <span class="highlight-phrase">Keyless Entry Transmitter</span> Programming/ Deleting - Manual Method</h3> NOTE: The <span class="highlight-phrase">keyless transmitter</span> attaches to the ignition key and is separate from the immobilizer transponder. It is not necessary to use the HDS when replacing or deleting an existing transmitter. <ul class="unordered"> <li>Adding a key (transponder) can only be done with the HDS. If the key being added has a new <span class="highlight-phrase">remote transmitter</span>.</li> <li>If one or all keys (transponders) are lost, the remote transmitters must be deleted manually. This will assure that all of the old keyless transmitters have been cleared from the keyless receiver unit memory.</li> <li>When replacing the power window master switch (has built-in keyless receiver unit), you must have all of the remote transmitters that need to be programmed to the car.</li> <li>The keyless receiver unit can only store 5 keyless transmitters.</li> <li>During programming, pushing the same remote button 5 times will delete all other remotes.</li> </ul> <h3></h3> <h3>Adding a Single <span class="highlight-phrase">remote transmitter</span></h3> Turn the ignition switch to ON (II), push the transmitter's lock or unlock button within 4 seconds and turn the ignition switch to LOCK (0), turn it back to ON (II) within 4 seconds and back to LOCK (0). Repeat this 2 more times and the locks should cycle when the transmitter button is pushed. Turn the ignition switch to LOCK (0) and remove the key. Wait 10 seconds and verify that all remotes function properly. &nbsp; <h3>Adding multiple (More than ONE) remote transmitters</h3> Turn the ignition switch to ON (II), push the transmitter's lock or unlock button within 4 seconds and turn the ignition switch to LOCK (0), turn it back to ON (II) within 4 seconds and back to LOCK (0). Repeat this 2 more times and the locks should cycle when the transmitter button is pushed. Push the lock or unlock button on each remote to be programmed within 4seconds of each other. Turn the ignition switch to LOCK (0) and remove the key. Wait 10 seconds and verify that all remotes being programmed are functioning properly. &nbsp; <h3>Deleting remotes</h3> Turn the ignition switch to ON (II), push the transmitter's lock or unlock button within 4 seconds and turn the ignition switch to LOCK (0), turn it back to ON (II) within 4 seconds and back to LOCK (0). Repeat this 2 more times and the locks should cycle when the transmitter button is pushed. Push the same button 5 more times. This will leave only the current remote programmed in the keyless receiver unit.
