lx470 2001 horn button broke

does anyone know how to replace horn on steering wheel. The horn button broke when I hit it. To replace the whole airbag and horn is very expensive just want to replace horn.

The horn pad on the 2000 LS400 I drove for many years "froze" about 10 years ago when I struck it hard to alert someone backing out of a parking space.  The indie Lexus repair shop I used for 20 years was unable to repair the horn button feature of the pad but quickly found a salvaged horn pad/air bag assembly that solved the problem.  Back then, the total cost of the the repair was around $800 if I remember correctly.  The horn pad/air bag assembly on the 2000 LS400 is held together by rivets which meant that it could not be disassembled for a repair attempt.  It's probably the same for your 2001 LX470.
