Adding a Timer to an Electronic Pet Door

Are you looking for a pet door with a timer feature? It will allow you to control exactly what time you want your dog or cat to be able to use their electronic pet door. Some pet doors, like this SureFlap Microchip Pet Door, already has a timer built in which makes it a programmable pet door. But if you have a medium or larger sized dog, there are currently no pre-installed timer options available.  In addition you could use one of these methods on a dog cage or crate door to allow them in and out during specific times of the day.

The dog doors that we recommend using are the High Tech Power Pet Automatic Pet Door and the Plexidor Electronic Pet Door.

Here is a solution on how to add a timer to your electronic pet doors. Keep in mind that if your dog is still outside when the timer turns off, they will not be able to come in through the dog door.

Here is a step-by-step guide on how you can add a timer to your electronic pet door.

1) Purchase a timer

Usually a digital or light timer works best. If you are still unsure of which one to purchase, you can ask your local hardware store where you might find the timers for Christmas lights. We also recommend the type of light timers that can plug into an outlet so easy installation.  Most are pretty manual so you won’t be getting a programmable dog door, but something more like a semi-automated door.

The timer we used in our example is the Defiant Indoor Heavy Duty Timer purchased at the local hardware store.

2) Program timer for the timer period that you want the pet door to stay on

This steps differs depending on what type of dog door timer you purchase. Generally, following the instructions provided by the product is a good idea. For our timer, we programmed the timer by pushing down the pins of the times we don’t want the pet door to be used.

3) Plug the timer into the wall, then plug the pet door into the timer

Since the timer we have is an outlet timer, we installed it by plugging the timer into the closest outlet to the installation location. An extension cord may be necessary if there are no outlets close by. Once the timer is programmed and plugged in, plug the pet door adapter into the outlet on the timer. Finally make sure everything is turned on, relax, and watch the timer do its job.

4) Test the pet door to make sure it works

Have your pet try the to use the timed pet door during the the ‘on” period and the “off” period to make sure the timer is functioning correctly. If it is not, there may be some troubleshooting needed. The best way to go about this is to make sure that you have programmed the timer and the pet door correctly. If there is still some problems, we recommend that you contact the timer manufacturer for timer related questions and contact us for pet door related questions.  Note if you do upgrade your dog door with timer functionality, once the timer locks the pet door will not open in either direction.
