Best KeyLocker doesn’t contain Help; the e-mail to contact a developer - support@smartphoneware.com The support department works efficiently sending the e-mail in the course of 1 business day.
Handy Keylock Help file contains comprehensible information to navigate in the application; for additional questions or suggestions turn to 911@penreader.com to receive any help from the support department, you will have to fill in the detailed on-line request, what I guess takes time and is not very comfortable for the user, as just sending the e-mail.
The Help file included into KeypadLock application will help you to orient yourself in it; support e-mail - contact@tektronic.ro The answer to any question about the application is delivered by the support department in the course of about one business day.

Best KeyLocker – the main screen has the following view:

When clicking left soft key Options you will see the following list of buttons:

• Activate – to activate/deactivate the application

This application is very easy to use. To make the right use of it first of all you turn it on in the main screen by clicking the Activate button. Then you have to define the needed for you lock timeout, after which the Best KeyLocker will lock the phone.
In this application I liked the possibility to choose the sound of lock/unlock action. It really works, and when the lock timeout comes, the phones locks with the previously chosen by you sound (or unlocks with the corresponding sound notification).
The possibility to lock the phone in apps or in chosen profiles is also very important and works great in this software.
To simplify your work with Best KeyLocker you can define the hotkey combination for quick locking or unlocking (one combination for two actions).

When the keypad is being locked by KeypadLock the screen has the following view:

• Sound on unlock – to select the sound notification on unlock action
• Lock in profiles – rule to lock in different profiles
Unfortunately Handy Keylock and KeypadLock applications so far can’t offer really interesting features.
Mr. Lock offers one interesting feature, which allows you to choose not to lock the keypad when you are running a particular application, just select the needed applications from the list of the available.

Test winner according to the overall application test is Best KeyLocker by Smartphoneware.
After updating review with the new key locker called Mr. Lock from MobiFunSoft, Best KeyLocker remains the winner of this review for being not only efficient but also for offering nice features. Best of all I liked the possibility of choosing the sound notification for lock/unlock actions.
But still Mr. Lock is the silver winner. This key locker is very convenient for allowing to define the profiles in which Mr. Lock is enabled and the possibility to select particular applications when the keypad won’t be locked. As a whole Mr. Lock is easy to use and free to download.
It’s inconvenient when user can’t try the application before purchasing it, as in case of KeypadLock software. But still this key locker has nice interface, good set of settings options and the Play Sound function, though just for the lock action.
Handy Keylock works well and is very simple in using. But it can’t boast though some interesting features, which are much in demand for most users.
