Using SE/SS key on house front door?

Well, a lot of the "rolling code" transponders out there are 40 bit TI chipsets, so nothing too exotic there. However, I don't think the radio frequencyis compatible.

The closest thing to what you want to accomplish is using the Prius Homelink system to interface to your home.

 

Some of the RFID house door locks I've read about come with a transponder that's meant to be stuck to the inside of your cell phone - something most people carry with them every day. I would think you should be able to find one that might have a transponder small enough to perhaps attach to the prius fob - but I have no clue if there'd be any interferrence from the two, etc. I too have been quite interested in going this route - either this or a biometric fingerprint reader (which now sell for less than $200 for your house).

An alternative is the punch code locks (Weisner? makes one for $100). It works with two settable codes. That way, you can set a code for guests or contractors; and change it later. Using this, you don't have to worry about leaving a fob or cellphone or anything. You do have to push some buttons though. (Better than whipping out a key!)

 

I lived at a place with a punch code lock. The only problem is that the punch keys may appear cleaner or dirtier or have a little more wear than the rest of the keys. A friend on mine was able to beat the system in about a minute. We only had a four key code. Just something to consider if you get this type of lock.
