You need a RS TATA Ring. They work all the time for me.

What is & Where do I find a TATA Ring?  The suppliers I purchase from has not heard of a TATA Ring...........

I was told to use aFactory Ring.......... If anyone knows Part Number, please PostThanks again

Also......Does the Key Sense wire need to be Powered?? If so, what Color wire & is it + or -?? Thanks

Did you have to put a key in a box then use a ring around the factory ring?

This is the part we call for: RS-TATA.IV Key in a box with a ring.

Yes.... the Pass4 & the DEI Unit require a Key and a Ring around the Cylinder.

Car will start every time the Key is in the Ignition all the way.  I am wondering if it is the Key Sense????Any color on the Key Sense wire?

Get some speaker wire ( a pair ) strip about 2 1/2 feet and twist it together and rap it around the transponder rec. make sure it goes around the rec not a light thing (if you have 1) around the IGN. Then use the plug that came with the BP and put the speaker wire in to the BP. Make sure you rap the Rec bout 5 times or more. Then test it. If that dont work then get the TATA
