Secure keyless entry system

Abstract

A secure keyless entry system integrates into an existing motorized garage door opening system to replace the one button transmitters typically placed in a vehicle. The one button transmitters are replaced with remote modules having alpha numeric key pads. The remote modules accept a string of input and compare the last four to eight entries to a previously set designated PIN. In order to obfuscate the designated PIN from on lookers, a user of the system may first enter a random string of decoy characters before finally entering the designated PIN. The disclosed system may also be used to replace the metal keys typically used to secure entry doors to a dwelling.

What is claimed is: 
     
         1 . A method of securing a door, the method comprising:
 a) installing a control module to an existing garage door opening system, the control module having means of controlling the opening and closing of an existing garage door, and the control module having means of accepting a radio frequency signal from a remote module and having means of receiving a radio frequency signal from the remote module, the remote module having means of sending and receiving radio frequency signals to and from the control module;   b) synchronizing the control module to a code system of operation used by the existing garage door opening system;   c) synchronizing the remote module to the code system of operation previously obtained by the control module;   d) entering a string of alpha numeric information into the remote module to create a designated PIN (Personal Identification Number); and   e) using the remote module in a manner to obfuscate the designated PIN by entering a string of alpha numeric information not comprising the designated PIN, prior to entering the designated PIN into the remote module, the remote module having means to store and process the most current string of alpha numeric information and to ignore leading alpha numeric information.   
     
     
         2 . The method of  claim 1 , further comprising the step of resetting the designated pin on a periodic basis so as to accommodate the use of a remote module by other individuals who are scheduled to enter a protected premises on a scheduled basis. 
     
     
         3 . The method of  claim 1  further comprising the step of using a pound key or other designated key to trigger the remote module to process the most current string of entered alpha numeric information to determine if the current string of entered alpha numeric information matches the designated PIN. 
     
     
         4 . A system for securing garage doors and other doors of entry into a dwelling, after a foreclosure or other involuntary repossession of the dwelling, the system comprising:
 a) a control module, having means of:
 i) integration into an existing motorized garage door opener system by use of and connection to two interior garage door button wires; 
 ii) replacing an existing interior garage door button; 
 iii) wireless communication with a remote module; 
 iv) synchronization with the code control system of an existing motorized garage door opener system; 
   b) the control module comprising:
 i) an antenna, learning switch, door opening switch, status indicator light, female connector assembly to accept a male connector assembly, with the male connector assembly having means to retain and connect with two existing wires of the existing interior garage door button wiring, and wherein the door opening switch rests in a off position or normal condition so as to not activate the garage door, and wherein pressure applied to the door opening switch will result in the door opening switch being placed in an on position or working condition, so as to operate the garage door, a door opener switching assembly comprising means of placing the door opening switch in a on position or an off position, two or more rabbit ear attachment points, and fastening screws; 
   c) an electrical adapter, suitable for supplying power to the control module;   d) a remote module, with an alpha numeric key pad, a key pad marked “enter”;   e) the remote module having means of:
 i) of wireless communication with the control module; 
 ii) accepting a designated PIN (Personal Identification Number); 
 iii) operating the garage door via wireless communication with the control module, with such operation triggered by entry of the designated PIN with or without the prior entry of false strings used to obfuscate the designated PIN. 
   
     
     
         5 . The system of  claim 4 , further comprising printed instructions suitable for use by a foreclosing lender in assembling the components of the system. 
     
     
         6 . The system of  claim 4 , further comprising an exterior door locking assembly with means of locking and unlocking an exterior front door or other door of a dwelling, the door locking assembly having means of wireless communication with the remote module. 
     
     
         7 . The system of  claim 4  wherein the remote module has means to execute a first command to operate a garage door after entry of a designated PIN, and means to execute a second command to operate the garage door in a reverse direction as compared to the first command, and wherein the second command will be executed without reentry of a designated PIN, as long as the second command is entered within a period of 10 to 20 seconds after the first command. 
     
     
         8 . The system of  claim 7  wherein two taps to the enter button of the remote module are required to execute the second command without reentry of the designated PIN. 
     
     
         9 . The system of  claim 4  wherein five incorrect entries entered into the remote module will disable the system and require a synchronization of the control module to the with the code control system of an existing motorized garage door opener system.
