TIS Lexus is250

[bioggy]

I got a Lexus is250 to program a key to all keys are lost I tried zedfull fvdi and xtool they reset it, it says takes 16 mins but won’t program it in, so I decided to use TIS but I did notice it needs a seed code calculator I am not sure if there is one built in. If any one could advise I would appreciate it. I am also using a oem remote for it. It is a smart key.

no there is no built in calculator

it wont program it in because its probably the wrong key...........................

where did you get the key from?

I did check tango has the calculator built in, and I had it from 3d group. I just bought another and virginised it, it is the same key so I don't know why the other didn't work but I plan on trying it out tomorrow or thursday, I will be trying TIS aswell as xtool because out of the 3 xtool actually done the job more or less but TIS is first on my list.

I did post the readings of the 2 keys, oem from 3d group purchased and the original one I virginised.

Only difference is one is 80 and one is 40, this being my first lexus makes it harder because I purchased with the exact car and they said this is the one unless the one I purchased from ebay and virginised (40 bit) is the one it needs and they sold me the wrong one.

The first one 40bit is the right key - on back side must have text 14AAC
