Denso Transponder And Key For Lexus Ls400


Recommended Posts


First question is did you get the master key i.e. the one that has 3 buttons and opens the boot? Because without this you cannot program any more keys if you buy them.

Have a look here for keys (nothing in the UK)

STEVE, THANKS FOR REPLYING. YES HAVE MASTER KEY WITH THREE BUTTONS AND ONE OPENS THE BOOT. I HAVE ALSO THE KEY NUMBER.

WILL TAKE YOUR ADVICE AND KEEP THE CLUB/YOU INFORMED.

I HAVE BEEN WITH THE CLUB FOR ALMOST TWO YEARS AND THIS IS THE FIRST TIME I HAVE ASKED QUESTIONS[, AND MOST IMPRESSED BY THE PROMPT RESONSE.

MANY THANKS,

You can buy blank Denso keys from Ebay for around a fiver, and have them cut by any reasonable security locksmith. (I would suggest avoiding the Cobblers type of key cutting service though).

If you buy a complete key, make sure it has a triangle detent in the "Unlock" section, a Dot in Lock and a white car/boot symbol in the third. The ones without the triangle are more common, but do not operate the LS400.

I did this myself, and discovered the triangle after 2 aborted attempts..... I then bought a 2nd hand key (with triangle) and transferred the inner Denso electronic pack to one of the earlier cut key fobs, and hey presto! A breaker may have an "old" key with triangle (You only need the innards).

Once you have this done, search here for "key programming" or "pedal dance".
