Some tips I found with the key fob

[Natty Bumppo]

Some may already know these tips,  this is on my 2021 Lexus ES350 and should work on others: 

1) Came across a video that provided a tip on protecting the car from theft when say in a very busy parking lot, or in extended parking, or just wanting to save key fob battery use when the car is not in use for a spell. Also useful on a spare key fob to save battery life. 

When you leave the car and all doors closed press and hold the Lock Icon on the key fob, then press the Unlock Icon twice then release the Lock Icon.  A red light will flash twice on the fob, now car is locked and even you cannot get in with the fob in your possession. This process stops the continuous 24/7 signal being transmitted from the key fob and not in free space for others to snatch the signal. To reactivate press the key fob Unlock Icon once. 

 2) I found this by doing what I do on my 1998 Infiniti I30 (bought in 2000 now with 185k miles great car ages fairly well for 24 years old). When approaching your locked car and say you have passengers, pressing the Unlock Icon twice unlocks all doors.   

I would like a key fob press condition that allowed the driver and passenger windows to go down when approaching the locked car outside on a hot Florida day. My Infiniti I30 has that feature by pressing and holding down the Unlock Icon on the key fob and down goes both those windows.  

If this feature is available on the Lexus key fob let me know. 

These are not the only key fob tips.
