Less secure.

Check the YouTube channel 'the lockpicking lawyer". He picks locks, both mechanical and electrical. His typical videos don’t take more than 2-3 minute because that’s all he needs to pick a lock multiple times. Electrical locks usually are opened with a paperclip or something similar. Wat too many locks are designed and built by idiots who have no idea about security

From what I’ve seen? Considerably less secure.

Many of them feature a normal pin-tumbler lock cylinder as a backup in case the electronics fail, and best case scenario it’s going to be as mediocre as any old Kwikset hanging on the peg on the comedy aisle at Lowe’s. So you’re probably still vulnerable to key theft, key duplication, picking, combing, raking, jiggling, etc.

Then there’s the electronics. A surprising number of them rely on either a solenoid to directly operate the latch/bolt, or a relay that energizes a motor to do the same, both of these are vulnerable to attacks by magnets. A stupid number of them are vulnerable to disassembly attacks. There are trace evidence attacks such as looking at the keypad and noticing where all the fingerprints are, there’s just watching you dial the combination…

And the smart phone app driven ones…sure, let’s send a signal that means “I just got home” across the internet. That sounds safe.

It depends on your threat vector. In the academic sense they’re less secure but if you often loan out keys they’re more secure because you don’t have to give someone the key. If you often forget to lock the door they’re more secure because you can do it remotely.

More ways to open is leds secure than leds ways to open. That said if you have an unsecured window, then that is the weakest link of the chain.
