Key Fob And Chiming Issue

[pennyarcade]

2006 RX400H owner here.

I got into a front end collision (replaced front bumper and hood) and ever since I got my car back from the shop, it is doing something that I don't think it did before the collision.

I press the unlock button on the key fob:

• Once, there is no chime (no sound and lights) from the car. Driver door unlocks
• Twice, there is a chime (sound and lights) from the car. all doors unlock.

Isn't the car supposed to chime when I hit the unlock button once to open the driver door?

I hit the lock button once and all the doors lock and there is a chime.

Can someone with a similar model try it out and report back?

I have the same vehicle. Here is what happens when I lock/unlock the 400h with the key fob:

Lock - single chime, parking lights flash, all doors lock.

Unlock (once) - double chime, parking lights flash, driver's door unlocks.

Unlock (twice) - double chime, parking lights flash, all doors unlock.

There are separate chime buzzers in the front and rear of the 400h. Maybe the collision damaged the front buzzer. By the way, the dealer can program the settings to unlock all doors with one press of the unlock button on the fob (I like it much better that way).

Thanks for getting back to me on this maseace and Ron
