The service manager was absolutely right to warn you about this - a Honda Odyssey has lock enclosures that are designed to prevent any kind of opening without a key, so a slim jim would not work. However, one Honda Odyssey owner have came up with a useful way to ensure that they are never locked out:
Make a duplicate key at your local hardware store. This key will not start your car but if you are locked out it can be used to manually unlock your vehicle. This driver actually drilled a larger hole on the end and hid their key behind their license plate for ease of access wherever they traveled.
Of course you can always purchase duplicate keys and keep them in the house or entrust a friend or family member to hold on to it. If you find yourself locked out with no other options, you can call a locksmith or use roadside assistance
if you have it in your insurance policy. If you don’t have it and you frequently find yourself locked out of your car, now might be a great time to shop around using the Jerry
