Help to identify signal

[8um1c4]

I receive a lot of those decoded signals:

 10 [00] {54} b5 7f 17 fb 7b b4 40 
  5 [00] {54} b5 7f 27 fb 78 fb 0c 
  5 [00] {54} b5 7f 27 fb 78 0f 34 
  2 [00] {54} b5 7f 27 fb 7e 81 04 
 10 [00] {54} b5 7f 47 fb 7e 5a 10 
  5 [00] {54} b5 7f 47 fb 7a d6 64 
  5 [00] {54} b5 7f 47 fb 79 38 2c 
  3 [00] {54} b5 7f 47 fb 7d b4 c8 
 20 [00] {54} b5 7f 27 fb 7c e9 8c 
 11 [00] {54} b5 7f 27 fb 7a 15 58 
  9 [00] {54} b5 7f 17 fb 7a 9a e4 
  3 [00] {54} b5 7f 47 fb 7b 23 fc 
  1 [00] {54} b5 7f 47 fb 7f af fc 
  5 [00] {54} b5 7f 47 fb 7c e1 e4 
  5 [00] {54} b5 7f 47 fb 7c 1d 18 
  5 [00] {54} b5 7f 47 fb 7e 5e e8 
  5 [00] {54} b5 7f 47 fb 7d d0 84 
  5 [00] {54} b5 7f 17 fb 78 6b b8 
  5 [00] {54} b5 7f 27 fb 78 e7 a4 
 10 [00] {54} b5 7f 27 fb 7a 19 a8 
  5 [00] {54} b5 7f 17 fb 7a 95 74 
  4 [00] {54} b5 7f 17 fb 7d 5a d0 
  3 [00] {54} b5 7f 27 fb 7d d6 b8 
  3 [00] {54} b5 7f 27 fb 7b 50 98 
  3 [00] {54} b5 7f 17 fb 7e f1 50 
  3 [00] {54} b5 7f 27 fb 7f 4c a8 
  5 [00] {54} b5 7f 17 fb 78 23 e8 
  5 [00] {54} b5 7f 27 fb 7c af e8 
  1 [00] {54} b5 7f 27 fb 7a 61 f8 
  5 [00] {54} b5 7f 27 fb 7e ed 08 
  5 [00] {54} b5 7f 17 fb 7d 12 a4 
  5 [00] {54} b5 7f 27 fb 7d 1e 08 

I don't know the origin, but it seems to be a garage or gate.

Some conclusions:

• The 10th digit (count from the right of course) is always 1, 2 or 4. Could bt command ID or button ID.
• Only the last 5 digits have different values
• The 5th digit (count from right) has only values bigger than 9, so the first 2 bits are always 1 (11xx)
• The last digit has always values 0, 4 or 8, so last 2 bits are always 00.
• The number of bits with change are 16, so it could be a rolling code with 16 bits.
  11xx xxxx xxxx xxxx xx00

Is this familiar for someone?
After find the origin it could be included in decoded commands?

Thanks.

One of the signals decoded her:

https://triq.org/pdv/#AAB10402E0016C044C2BC48291A29291A291A291A292929292929291A291A1A1A29292929292929291A29291A292929291A29291A1A291A1A1A2929292929292929355

In rtl_433 appears: {54} b5 7f 47 fb 7b 23 fc
but in triq.ord appears {55} 5A BF 93 FD BE 8F 04

You could try a BitBench like this to inspect the signal (also try just v as format).
If you look closely at the pdv link you see it is indeed PWM 367/1100 but with preceeding gaps.
It looks like HCS200/HCS300 KeeLoq but we'd expect 66 bits.

Yeap, thanks for the help.
Only 16 buts are changing, so it can't be Keelog.
I don't know the source, so I have no way to test (trigger).

By the way the number on the left of [00] is the number of occurrences in the last 2 or 3 days
