Tesla 2025.45 quiet lock sound fix: get your volume back

Tesla's 2025.45.x update broke something that actually mattered to most of us — our lock sounds got way quieter. I noticed it immediately after the update hit my Model Y last week. What used to be a satisfying beep that I could hear from 20 feet away turned into this barely audible whisper.

Turns out I wasn't alone. The Tesla Motors Club forums exploded with complaints, and Cybertruck owners are especially pissed because their trucks went from having the loudest, most badass lock sounds to... basically nothing.

What Tesla changed in 2025.45.x

The update messed with the audio output levels for external speakers. Tesla probably did this to comply with some new noise regulation, but they overcorrected. Hard.

Before the update, lock sounds played at a reasonable volume that you could actually hear. Now they're so quiet that you'll miss them if there's any ambient noise at all. Wind, traffic, even someone talking nearby will drown out your lock sound completely.

This affects all Tesla models running 2025.45.x firmware:

●Model S (2021+)

●Model 3 (all years with external speakers)

●Model X (2021+)

●Model Y (all years)

●Cybertruck (all deliveries so far)

Check your firmware version

Want to see if you're affected? Here's how to check:

1. Sit in your Tesla
2. Tap Controls on the touchscreen
3. Tap Software
4. Look for version number at the top

If you see anything starting with "2025.45", your lock sounds got nerfed.

The quick fix: boost your files with our converter

If you're using custom lock sounds, you can fix this yourself in about 2 minutes — right here on TeslaLockSound.com.

Our audio converter runs entirely in your browser (nothing gets uploaded to a server) and handles everything Tesla needs:

1. Go to our Convert tool
2. Upload your current lock sound file (MP3, WAV, OGG, M4A — whatever you've got)
3. Adjust the volume slider to boost it
4. Trim to 5 seconds if needed
5. Hit convert — it exports as a properly formatted LockChime.wav (44.1kHz, 16-bit)

That's it. No downloading Audacity, no fiddling with normalize settings, no wondering if you got the WAV format right. The converter handles the Tesla-specific formatting automatically.

The even easier fix: download pre-optimized sounds

If you don't want to mess with converting at all, just grab something that's already done.

Every sound on TeslaLockSound.com gets volume-tuned for Tesla's speaker system. We test them on actual Teslas (I've got a Model Y and my buddy has a Cybertruck), and we adjust the levels so they sound good even after Tesla's audio processing.

Our sounds work perfectly with the 2025.45.x update because we saw this coming. Tesla's been gradually lowering external speaker volumes for months, so we've been compensating by tweaking our files to punch through.

Plus, you get sounds that are:

●Properly formatted (WAV, 44.1kHz, 16-bit)

●Tested on real Teslas

●Ready to install — no editing needed

●Way more interesting than the default beep

Browse our sound library and grab a few. The installation process is exactly the same as before — just copy to your USB drive and select in your Tesla's settings.

Why this happened (and it's not getting fixed)

Tesla didn't break this by accident. They're dealing with noise regulations in different countries and cities that are cracking down on unnecessary vehicle sounds. Electric cars are already quiet, and regulators don't want us adding more noise pollution.

The problem is Tesla applied this volume reduction globally instead of making it region-specific. So even if you live somewhere with no noise restrictions, you still get quiet lock sounds.

Don't expect Tesla to revert this in future updates. If anything, lock sounds might get even quieter as more places adopt noise ordinances. That's why the volume-boost fix is your best bet.

How to install fixed sounds

If you've never installed custom lock sounds before, it's actually simple:

1. Get a USB drive (any size works, formatted to FAT32 or exFAT)
2. Create a folder called "Boombox"
3. Put your WAV file inside, named LockChime.wav (our converter names it for you automatically)
4. Plug the USB into your Tesla's front center console port
5. Go to Controls → Safety & Security → Sentry Mode
6. Select your custom sound

What about other Tesla audio issues?

The 2025.45.x update affected more than just lock sounds. Some owners report:

●Quieter Boombox mode

●Reduced Sentry Mode alarm volume

●Softer turn signal sounds

●Summon sounds barely audible

The volume boost fix works for any of these if you're using custom sounds — just run them through our converter and crank the volume. For built-in Tesla sounds, you're stuck waiting for Tesla to address it (which probably won't happen).

Get your lock sound back

This whole situation is annoying, but it's fixable. Either boost your current sounds with our converter or download pre-optimized ones that already work with the new volume levels.

I switched to one of the louder Cybertruck-style sounds from our sound library after the update hit, and it's loud enough that I can actually hear it again. Sometimes Tesla's updates force us to upgrade our sounds too.

Browse the sound library for volume-optimized options, use the converter to fix your existing sounds, or check out the installation guide if you need help getting set up. Your lock sound is too important to live with Tesla's whisper-quiet default.
