I recommend locktech.
Locktech second lock is on the right hand side, so if you're right handed, will be much easier to insert the key and twist it to unlock the second lock.

Redbat second lock is on the left, so those righthanded people will struggle a little bit to insert and twist the key to unlock the second lock.

If the shop have both type of pedal locks available, you can try them before they install it in your ride

Better not to plug-in the wire harness of the steering lock into the car.
Last time my friend's car wouldn't start due to the faulty wire harness.
Had to ask the installer to come to his car.

Many installers also recommend not to plug the pedal lock wire harness to the car ignition.
