I surely understand the convenience of a keyless entry door but in the case with a PC, the keypad is positioned high making it easy for someone with binoculars to watch the code get punched-in. These days with such high quality cell phone video cameras, they can even record it from a long distance.
That doesn't worry anyone?
Worry? I guess it it depends on where you choose to enjoy your PC. Perhaps it's best to avoid questionable locations.

In 20 years of RVing, we have never had an issue of someone trying to enter any of our 4 RVs. . .and as fulltimers, we have traveled widely across America. Believe me, if someone is so intent on entering your rig by watching you with binoculars punch in a door code, they will get in anyway. We have never overnighted in Walmart or any other retail parking lot. We use regular RV parks whenever we don't stay in a CoE, city, county, state or national RV park. If we want economy, there's always Passport America.
We do take caution with leaving high priced valuables (generator when we had trailers, unlocked surge protectors, etc.) accessible to the opportunistic thief. We have never had a lounge chair, Baby Q, dog tether, camp table, or anything else stolen when we leave them outside the rig, even when we leave the site for whatever reason. Not saying it won't happen sometime, but we don't let worring about "things" spoil an otherwise enjoyable lifestyle. Prudence is necessary; locks are necessary; undue worry about things and stuff out of your control is not necessary. Just sayin'. . . Happy trails.
