Digital or conventional locks are using similar lock mechanism.
Digital lock is merely having a motor to automate lock and unlock operations.
Hence, the security level is comparable to conventional lock.
For Samsung push/pull lock, it's safer to get it from local supplier but the price is significantly higher.
There are many cheaper "imported set" but the risk is the pull/push direction may be incompatible with Malaysian's door. Please make sure you check this.
And there are also higher risk of faulty mainboard in older model... not sure the new one.
