Lost a Lic, Key & Fob all in a bag together. Whoever has the bag has the address & a key for the car. How do I secure the car now?

also I know I can program the new fob, who other than Honda can cut the key & for how much?

Thanks & Happy New Year!

thank you!

is there a difference physical or electrical -between the black key and a grey key? is grey always the valet?

There is no difference except color.
The cut of the pattern is different if one wants it to be a valet key.


On the immobilizer, a dealer can erase transponder codes for the lost/missing keys so even if someone can get inside, it will not run.
They will need all of your working keys.

IF the LOST key was stamped T5 (a cloned key) OR the original of that which was cloned, then it will always start the car if it's "twin" is still able to start the car.

A further explanation of this ^^^^post.

This generation of anti-theft used a fixed code that was unique to each individual key. For convenience lets say the lost key was coded "ABACD." Honda offered keys (and so did some companies such as ILCO) that had no key code assigned to them. These were known as T5 keys. You took a key and placed it into a special machine and it read the code and then programmed that key code into the blank key.

The problem is that you can have as many keys with ABACD (or whatever code desired) as you want. So if the lost key had a partner with the exact same coding the lost key will be able to start the car. The only way to prevent this would be to not program the matching key into the system. Of course there really isn't any way to determine which keys are cloned and which are not. This issue has been a minor worry of mine for about 5 years since my car came with 5 keys, 2 of which were T5 clones.
