If it's just a matter of locking your chipped key in the car, here's a simple/cheap solution that worked with my '00 Accord which didn't stop me from locking my keys inside, the way my '16 prevents that.
Get a hardware store to make a cheap, non-chipped copy of your chipped key. Put that non-chipped key in a magnetic "hide-a-key" case and hide it somewhere on the outside of the car where it won't fall off when you hit bumps but is still easily accessible.
I put it behind the front grille on my '00 in an angled, magnetic spot that held it securely in place for 16 years. If (OK, whenever) I locked myself out, I grabbed the hidden key, opened the door and rescued myself.
The non-chipped spare won't start the engine, so even if somebody finds it, they can't steal the car, unless you leave the chipped key inside. Just don't put a chipped key in a hide-a-key box because it may get wet and that can damage the circuitry inside.
If you're afraid you might lose your chipped key, rather than just locking it inside, also hide a spare chipped key somewhere inside. If you lose the chipped key, use the non-chipped key to open the door/trunk and retrieve the spare chipped key from its hiding place. That key came in handy when someone pushed me in a pool with the chipped key in my pocket and then it manually opened the door but wouldn't start the engine...
