Sure you can. We bought a new 2005 Toyota Camry SE last November. It also has a chip embedded in the keys, we received two such keys and what Toyota calls a "Valet key" that has no chip, just a plain key.
I'm not sure of the role the valet key has but has something too do with a valet parking your car and not being able too access the trunk or glove compartment I think. I need too read up on it some more too fully understand its role.
I'm pretty sure that you have too disable the alarm and starting apparatus though.
Reading a new car owner's manual these days is an education unto itself!
It took me a week too get through it all and I really need to read it again to get its full effect.

:grumpy:
We also received a "Credit Card" key that is basically a piece of plastic the same size as a credit card with a key cutout. The "key" has too be cut at Toyota on their machine using one of the embeded chip keys.
Our salesperson didn't know how too use it when we first bought our car but we were in for an oil change just last week and she fixed us up then.
I asked for and received an extra credit card key so both my wife and I could each have one.
If I were in your position I'd be asking the dealer if there wasn't some way to be able to carry a spare key on my person.
